Supporting The Forum / MOVED: bencutLaser does'nt open .dxf

Is there a German speaker that would be willing to help a fellow German out, he's having problems converting to Grbl 0.9.

It may be because his board doesn't have the jumper or he hasn't correctly loaded the firmware.

Send me a PM if you can help. Thanks!

T2 Engraving / Bezier curves
« on: January 07, 2017, 07:42:21 AM »
Back in v1.3c I added support for most of the common DXF entities, which included splines and beziers (curves and other shapes were already supported, the only exception is text).

I don't really use beziers myself but following a post over on the BCL thread I did some testing.

Here's a quick example using TurboCAD, the bezier imports perfectly.

I've noticed that some programs don't do a great job of exporting them accurately in which case they won't be correct in T2Laser but I can't fix what another program does incorrectly. It will depend on the CAD software, in particular I've noticed some odd errors with Inkscape but not always. So I still recommend converting to polylines or curves when exporting.

General Discussion / Why you shouldn't leave a laser unattended
« on: December 12, 2016, 09:12:56 AM »
A user of T2Laser contacted me regarding this unfortunate incident.

He left the machine for around 15-20 minutes and came back to a blazing fire!

It was apparently cutting "foam", which doesn't sound very safe to begin with, but it is a good reminder to everyone.

Obviously we do not know the cause but he said the machine had stopped once before with the laser on and he suspects the same happened here. I asked about power savings and he said the settings were changed to not sleep but of course that doesn't mean the USB ports weren't powered down or something else happened to cause it.

Kits / IIIP Maker Select
« on: November 30, 2016, 03:11:29 PM »
I asked for advice on which printer to buy, for a complete newbie.

Thanks to Pawpawpaw85 and others I decided to purchase the Monoprice Maker Select v2. It's a rebranded Wanhao Duplicator i3 which is itself a Prusa Mendel i3 clone (pretty typical machine).

It came with a customized Cura 15.04, a very good manual and getting started guide, both printed and on an SD-card.

My first impressions were it's a very professional look and feel out of the box, full metal frame and solid drive gear / electronics. Assembly was practically nothing, 4 screws to get the machine together and a couple of motor / limit plugs to connect. It probably took 5 minutes, and then leveling was a breeze and within 30 minutes I was printing one of their sample files.

It adhered to their "special" bed mat (not sure what it's called) perfectly and the print was excellent, I was blown away by the quality considering I had no idea what I was doing.

If anyone wants a cheap and very novice friendly machine then I would also suggest this product. I'm currently printing some "upgrade" parts that were recommended.

Controller Boards / Differences
« on: November 20, 2016, 05:14:47 PM »
Most of the cheaper systems seem to be using ANet or Melzi controller boards (all-in-one) rather than the Mega2560 and RAMPS boards.

What are your thoughts on these?

If you have any links to i3 type machines that are a good buy I'd be very interested.

Also, is there anything else I should be looking for. Like self leveling or dual extruders etc.

General Discussion / different machine
« on: November 11, 2016, 04:34:59 AM »
Does anyone have experience with this machine: goo.gl/TfsZAq

It obviously uses different firmware, perhaps a clone of the LaserAxe?

If you have a hex that is suitable would you post it.

Thanks!

T2 Engraving / Shows "Connected" but not "Grbl Ready"
« on: October 20, 2016, 05:14:11 AM »
This means the COM port was opened but Grbl isn't responding.

I was able to flash the firmware, but still couldn't connect. I tried another cable, same thing.

I went to Device Manager and saw it had a generic COM port in the Ports section, but there was also a "USB 2.0 Serial" listed under Other devices.

I clicked on it and selected to update driver, chose search automatically and waited. After a few seconds it started to update the driver and on completion it showed USB-SERIAL CH340 was updated successfully and now it appears correctly in the Ports (COM & LPT) section and is gone from Other devices, but more importantly, it works!

I'm guessing that Windows initially installed a generic driver that wasn't fully compatible. I also had to re-scan the COM ports and select the new one that showed up as a different COM port number.

General Discussion / now that's a laser...

Interesting use, and it claims no harm to skin... I'm not going to test that claim.

General Discussion / Laserable Plastic
« on: August 28, 2016, 10:23:36 AM »
I've been using Rowmark laserable plastic but last week I decided to try the Bur-Lane brand as I got a good deal on it.

http://www.bur-lane.com/bur-lane-series-laserables

The results were very good, nice clean marking at least on the black over white that I used.

I used speed 800 on my 2500mW laser.

(attached are immediately after engraving, they could probably use a quick clean-up but look great already)

T2 Engraving / T2Laser new features
« on: August 14, 2016, 08:06:34 AM »
The T2Laser license allows all registered users free upgrades for 1 year, so unlike most software that requires you to purchase an upgrade each time new features are added these additions are free for everyone  8)

I have already written the code and will be doing extensive testing over the next couple of days before releasing a beta for you all to test. Before I release it, I am looking for some feedback.

So we're all on the same page, raster means it is engraved/scanned and vector means it is either cut or engraved as a line.

I'm calling it Sketch Plus and it supports the following:

1. Overlay filled Sketch on an Image - the result is a combined raster job (so you can quickly add text to your images)
2. Add vector Sketch to an Image - results in a raster image combined with vector Sketch (used for cut out?).
3. Add vector Sketch to a filled Sketch - the result is a raster Sketch combined with vector Sketch, could be used to "crisp" up the edges of a Sketch as a quick way to produce filled text.
4. Image with contour cut - results in a raster image followed by traced vector

So now, with Sketch you have 6 modes including the previous Sketch vector and Sketch Filled raster output.

My question, am I missing anything? While I'm working on the Sketch code I'd like to make any other improvements.

In the trace module I now allow you to use zoom, I still think you get better results with 1:1 view but after some testing the difference is negligible so I have enabled it. It now uses the output for #4 above.

There are many small updates and bug fixes in addition to the above, I am now correctly supporting transparent png images  and have fixed some of the sub-form open locations. The simulation "View" can skip laser off lines (previously drawn as yellow).

I truly appreciate everyone's support and thought I would share this map of registered users.

I hope to continue adding laser blasts all over the world.

T2 Engraving / Ich brauche Hilfe von deutschen Sprechern
« on: May 26, 2016, 09:29:42 AM »
I have a German speaking user that is having some trouble getting T2Laser to work.

I gave him the forum link but because he doesn't speak any English he is not comfortable to use translation to request help.

Would anyone be willing to help him by e-mail?

Please PM me if you can, and I will forward you his information.

Thank you,
Zax
