Assembly Help / Re: Stock Eleksmaker laser height.
« on: June 25, 2017, 06:44:24 PM »
I made longer legs for my Eleksmaker out of acrylic. I did them on the CNC so all I have is a DXF file but with most cad programs you can add height to them so you can 3D print them.
If I find time I will see if I can make an stl file if that is what some one wants.

It can also be caused by to small a power supply. I had this problem and at least one other person in the forum solved the problem by going to a larger power supply.

Looking good, I have been testing out the CNC mode using a raster image (jpg) and cut small - 60mm wide.

Using a v bit and a .2mm deep cut I got the following image. The cut is a little wide using the V-bit and can't wait to get my small one's later today. But this is the best I have ever been able to engrave from an image with the CNC machine.

T2 Engraving / Re: Can't control laser w/Mana SE board
« on: June 22, 2017, 04:46:40 PM »
So I ordered a new Mana SE board from EleksMaker and it arrived today; no bueno.  Exact same behavior as before (laser on full blast all the time).  I'm going to order a 2500 mW laser from Eleks and see if that works.  I'm figuring I have zero chance of getting a replacement laser from BangGood; irritating to think I have a 5500 mW laser that won't work properly (unless I want to burn holes in stuff).
Do your self a favor and don't spend money yet.

Get a small 12V bulb and a 6V bulb and wire them up like the laser. 12V bulb between + and -, and the 6V bulb between S and -. Then make sure that you can control the 6V bulb from the controller. With this setup you can test everything in the system to make sure its all working properly without actually having a laser hooked up and a lot safer.

If the bulbs work properly and the laser does not - then it time for a new laser, but not until then.

The timing is good, I liked the results I was getting with the previous beta code so I ordered a full set of very small bits for the CNC .6mm - 1.5mm and they should be here tomorrow afternoon (go to love Amazon Prime). Hope to have some nice results to show soon.

Well it is a beta :)

Suspect that is the com port area, mine has been opening up as an unpopulated combobox and I have to manually type a com port in, thats if the com port area shows up, a few times it has just been blank in that whole region, no comport or baud rate.

Zax, is there any easy way to rollback to a previous version ?

That is strange because I had it working fine on 2 computers. The first time startup I needed the drop down to get the port and after that it auto connected with no issues.

You probably have home switches enabled. If you do GRBL wants to find home prior to doing anything - thus the alarm.

OK with the safe travel for raster mode. What I did see is a line from home to where the raster was going to start so I got etching for all movement.

I run my machine like I am down under -- so that could be leading to the view issue.
-.3 cut depth and +1 for safe travel.

Get the variable spindle mode tested. I vector mode it works fine but in raster mode the spindle is never turned on with any setting. If I edit the Gcode and add the S argument to M3 it works fine.

Still testing but have some early results.

Vector mode all the cutting is fine, safe travel works great.

In Raster mode the safe travel does not work, still moving at Z0.

Also any time CNC mode is enabled the view screen does not show anything.

Back to testing, going to install my board and test the variable spindle next.

Re.: http://benboxlaser.us/index.php/topic,113.msg26482.html#msg26482

OK... it's alive!

v1.4k has been released, and includes the previous changes and those requested above. You can set a spindle speed as well as a dwell for the spindle to get up to speed. The Z-safe height feature was also added.

If you want to test it, click "Check for Update" and enter the magic password: jericho

It will release to everyone (without needing to click the link or enter anything) automatically in a few days to a week, after more extensive testing and feedback.

Please provide your feedback, especially if you requested the feature. Thanks!

I am about to go out for the night, but I did generate some Gcode and it looks exactly the way I would expect. Will fire up the CNC tomorrow.

Thanks

Thanks for the insight, my CNC is larger and uses a 110V trim router which has a speed controller (not controlled) and is only switched on/off by software.
...

No problem - I actually have two CNC's and the large one does use a trim router with air assist, mist lube and vacuum and with all those gets quite loud.

The smaller one (A3 size) has a 500W spindle that actually runs at up to 48 volts and is much quieter and nice for small jobs. I can sit and work without hearing protectors on. Its control/power supply as an input for a pot (variable resistor) or 0 - 10 volt input to control speed. I have a little board that takes TTL PWM and translates it to the output voltage.

I have been using Estlcam to play with some 3D work and when setting up a tool you set spindle speed, and it puts that speed value into an s command for m3. That is what got me to thinking about the variable speed for the spindle.

I found something else today with the CNC mode. I am about to set up my spindle to be controlled by the controller so I took a look at the nc code created in CNC mode.

I have included the start of the code generated. In the header it says Laser Power is 255 but when the M3 is actually send there is no S value included. It would be nice to be able to set the spindle speed. For now I will just use the manual gcode command to set the value that I want.

3D Printer Software / Re: 3D printer x/y steps per mm
« on: June 17, 2017, 05:03:19 PM »
the 80,80,400 are good starting points but none of these printers are exact.
You need to calibrate, and Method 2 is a little harder (trying to measure exactly how much the head moves) but is more accurate because the different plastic you use all have different amounts of shrinkage. But that being said if you always use the same plastic (which most of us do not do) you can get good results with method 1.

All of my printers were a few % off from the calculated numbers until calibrated.

 
Method 1)
With those numbers print a test cube (the bigger the better) and then measure it.

Find the ratio of what you got vs what you expected for each axis and use that fraction to adjust the numbers.

Repeat until happy.

Method 2)
Mark the rails and tell it to move something like 100mm. Again get the fraction of what you expect vs what you got, adjust and try again.

Give us the DXF file and tell us how big you think it is.
