Title: Feature Requests
Post by: jlauzon on May 17, 2016, 07:14:59 PM
1) multiple passes (vector only); allow custom user-entered number, sometimes we want more than the drop down allows.

2) raster image positioning; ability to move image to origin, far maximum, etc.

3) save-able settings profiles; for feedrate, laser power, engraving area, etc.

Thanks!

Thank you!

1. It was already on the list after I saw someone was doing 50 passes (wow!)
2. Not sure I understand the concept here, the lower left of the image is always the origin unless you choose centered.
3. These are saved in settings already, but I think you are suggesting profiles for different purposes - I like that idea

Ideas in the air.

I thought the same about save presets, also the software can suggest some, maybe?


Like:

Quality
Thiny Lines
Small sizes images
...


Fix this topic for suggestions?

I like to be able to position with a webcam that would be so cool. But I doubt that is easilyfeasible
Title: Re: Feature Requests
Post by: Zax on May 18, 2016, 09:00:34 AM
That's actually not too hard, most webcams support the same protocol so I could display the image and add cross hairs for alignment but there would need to be some calibration between the laser and camera - also possible.

Very interesting idea.

Ok, that webcam idea sounds cool.  That would make getting your material placement easy and accurate.  Mount the webcam on your gantry, place it in your home position, look to see if everything is lined up and send.

I totally agree with the savable settings.
You could save settings for Pine, Oak,  cutting paper, cutting balsa, etc.  Yeah, that would be very nice.

It's a feature that Glowforge has. And it looks really useful.

 Would it be possible to make an option to be able to use the arrow keys on the keyboard to jog the laser, I find myself going to my machine looking at its position and then going back to my computer to Click direction arrow which is somewhat tedious when positioning it before burning, If I could just have my fingers on the arrow keys while looking at the machine it would be easier
Title: Re: Feature Requests
Post by: Zax on May 19, 2016, 07:40:43 AM
The arrow keys already work, but only if "focus" is on the G-Code box.

So, when you open the laser control window they work but if you click home or jog using mouse click then you need to click in the big G-Code box to re-enable job. Also, if you have debug mode on they are disabled.

How do you turn on debug mode?  I guess I'm overlooking it.

OK, I will tell you but don't tell anyone else.

I promise I won't do anything stupid.  You've mentioned it several times, so it had me curious.
Title: Re: Feature Requests
Post by: dindunuffin on May 21, 2016, 12:51:00 AM
I have a simple request that I think would be very helpful.

When positioning the laser and setting home, it is somewhere between a guess and an estimation as to where the image will actually be etched.  What I would like you to implement is a button on the laser control page that will, at a high speed and low power, run a quick trace around the canvas frame.  In concept, it would be exactly like the setting that etches a frame around your picture, but it would do it 'on demand' and do it without actually etching anything.  For this feature, you could watch the trace and make sure everything is aligned where you think it is going to etch and that you have a good home, before you actually hit send and begin the etching. Basically, its a quick visual of the outside perimeter of your canvas.

Isn't that the "trace frame" feature?

LOL, I'm just not the brightest bulb.   Everything is in here, but I'm simply on the wrong wavelength.   I'm so used to Windows software having everything staring you right in the face with a big label on it. I'm blaming Microsoft for training me so poorly

I keep assuming I understand everything and then there's another "hidden" feature that I overlooked.   In my defense, the directions did not specify 'what' to right click.  I right clicked everything except the laser buttons, so I guess I gave up too quickly.

Admonishing myself, I will go back and go thru the entire manual.

Atta boy...I will join you..
You are not alone on the forum having BIG problems!!
...and as one who has read everything as it comes up I can tell you...you are either lucky getting the laser to work right away or just downright unlucky.

Welcome to one of the latter  gang!

If it weren't for Zax, I'd have given up a long time ago.  He really is the person responsible for getting most of us up and running.  And not to forget Ralph who put this forum together for all of us.  I hope I can learn enough to help others and yes I did go back and read ALL of the instructions one more time.
Title: Re: Feature Requests

What makes the glowforge so appealing to me is that it can use the webcam to auto center and auto rotate the image to the object. Plus in the use of "webcam" a very simple image sensor is all that is needed.  The weight added to the gantry would be negligible.  Im not talking about an of the shelf webcam.  Im thinking like a image sensor.  Bulk price from digikey is about 4 bucks,  or about $40 from adafruit for something that is ready to go.    Use the x gantry to take a "scan" of the work surface and then allow the user to position the image in the scan as desired.   Add a measuring tool in the software to help get things aligned. 

It would be a great secondary kit for someone to sell.  'Cough' Zax 'Cough'. 

Or if someone would just pick up a bulk amount of the A5 kits and pre set them up with grbl .9 and software + camera.

Post by: dindunuffin on June 24, 2016, 10:01:06 AM
Oooooh, a turnkey kit with everything included, even instructions.  I'm only aware of one real working piece of software and one in production for these lasers.  That's a better start than Bill Gates had with Microsoft and the PC.

I would like to request that the autozoom feature be allowed to work when using trace.

Thanks

Yeah, been there and done that... disabled it.

I am tracing using the displayed image, so when you are zoomed the resolution isn't correct and the trace looks terrible.

I'm already keeping multiple copies of the image in RAM so adding another copy to do the trace is going to cause issues, the ones I have currently are needed for other purposes and won't work either, so long story short... I tried, I failed.

It is still on my list to get back to at some time and figure out a better method, but no guarantees of success.

Hey zax is there any plan for implementing a measuring system within T2? Kind of how benbox has the mm marks on the edge of the screen? That would be nice because then I could engrave something so it would be easier to line up what was being engraved. Also the trace frame feature isn't working for me for some reason. I enable it and it doesn't trace, however I only have the trial version still because I just purchased it yesterday and havnt gotten my code yet. Am I doing something wrong? Or just after enabling it, it will then trace the frame and then start?
Title: Re: Feature Requests
Post by: Zax on August 31, 2016, 07:12:57 PM
Yes, adding rulers is on the list but will be added when I change the GUI. That's coming after features are added and stable. Currently you can see the extents, turn on the overlay on the design window or see the simulated view on the laser screen.

I'm not sure what you mean about enabling the frame, are you talking about the settings menu? That's to add a frame to the G-code, not to pre-draw it for alignment etc. You do that in the laser control screen using the manual laser buttons, check out the manual for information on that. It's fully functional in the trial.
Title: Re: Feature Requests
Post by: Kold on August 31, 2016, 08:46:23 PM
Sweet, Thanks! i was talking about The Engrave Frame Feature under settings. I was confusing that with the Trace Frame Feature. I didn't realize the engrave frame happens after the engraving. which is why i thought it didn't work. it definitely does. i had to re-read the manual but i found out that right clicking the laser off button does in fact trace the frame of the image before i start to help line stuff up! :D
Title: Re: Feature Requests
Post by: Zax on September 01, 2016, 05:01:34 AM
If you right click the laser on, it will draw the frame at the set power level. So you can set the power to 5 and just see the laser beam but not make a mark or increase power to actually burn the frame as you wish.

Hello,

I have a question: If I use the laser for engraving (raster), de two side of the picture (x max and x min position) allways darker/deeper then the other part of the picture. Why is that? Bug or phisics :)?
Title: Re: Feature Requests
Post by: Zax on September 03, 2016, 03:24:34 PM
It is caused by a gross mismatch between your speed (feed rate) being high and acceleration (also deceleration) value being low

Increase acceleration and it will be reduced, or lower for speed and they will be better balanced giving a more uniform result.

$120 is the x accel (mm/sec^2) and $121 is y accel, you should be able to use 600-800 without any problems, but it will depend how well setup your machine is. I run 1200 without seeing issues with speed up to 2000.

You can change these in T2Laser if you are registered, enable debug/advanced mode to bring up the manual g-code window and type in $120=800 and press enter, then repeat for $121=800 or whatever values you want to test.
Title: Re: Feature Requests
Post by: korikmate on September 04, 2016, 12:59:13 AM
Thank you Zax! I will give it a try. You mentioned that "without any problem". What can be a problem if the laser is not setted up well, or the speed is too high?
Title: Re: Feature Requests
Post by: korikmate on September 04, 2016, 02:37:52 AM
Another question: the x max x min problem is gone but why ia that the ear of the dog is darker than its face (picture)? The moving of the laser were horisontal.

Thank you!
Title: Re: Feature Requests
Post by: Zax on September 04, 2016, 04:38:28 AM
It's physics, Newton's first law that covers motion and inertia.

Increasing acceleration puts more stress on the machine when it changes direction, the mass wants to continue but the motors want to go the other way. This results in the belts stretching as they take more load, causing backlash where the head is behind it's desired position. You can get zig-zag patterns appearing or perhaps issues at the leading edge before the head catches up.

Having your machine setup correctly, with low friction and good belt tension will help a lot.

So for the dog, I'm not sure. When you say horizontal do you mean as the image is uploaded or perhaps it's rotated and you mean it was scanning vertically the way it's uploaded?

It could be material related or it more likely it's the laser heating up.

I have a feature request.
Can we have an option to leave the fan on for XX time after a job completes to help cool the laser?
My 3D printer has a similar feature, and it's helpful.
Title: Re: Feature Requests
Post by: beikeland on November 27, 2016, 07:33:08 PM
With the default board its not possible to have  the fan on without the laser also being on. Otherwise good idea I gusess, most advanced users will probably make a move towards proper ttl control.

As already mentioned, the fan is coupled to the laser so the only way is leaving the laser on at say power 1. Which isn't really a good idea.

I wired mine up differently,, I cut the wires to the fan and have it running off the 12V output on the board, so it runs all the time.
I also upgraded the fan, this keeps the laser nice and cool, and does a fairly good job of blowing the smoke clear also.
I also installed a second fan to really clear away the smoke, it has an on/off switch.

I didnt like the idea of the fan only running alittle bit as the laser was activated.

I'll be doing something like that when I finally get my replacement laser from bangood. Probably hook up some more mosfets to enable control via g codes for coolant etc. Seems regular Arduino sized cnc shields work as expected, but not Nano sized cnc shields - so getting closer to making this thing usefull
