T2 Engraving / Re: Y axis and X axis
« on: October 08, 2019, 05:02:47 AM »

Diagonal means it could have been friction causing the motors to stall and lose position, check the belts aren't too tight or you have something causing it to jam (did the cables snag?).

That's unusual, I could see one stepper doing it but both - are you using diagonal engraving?

It may have been a power spike (electrical noise) or a bad connection.

Did you use my firmware (Grbl 1.1e DEFAULT)?

I have never heard of a machine not working when using T2Laser and my default firmware.

Of course if you don't have it wired correctly then it may not work correctly.

Benbox is very old and doesn't support anything except the old modified Grbl 0.8, plus it won't support your Z-axis.

Add a 1kohm pull down resistor from TTL+ to GND and you'll get rid of that nasty laser pulse at start-up.

They’re all pretty much the same, just look for the features you need. The Eleks Mana is very popular but uses a very poor Nano clone (easily replaced). I like the Cronos Maker boards, they have a relay for a higher powered CNC spindle, a MOSFET and regular TTL/PWM output. The only negative is they use an embedded microcontroller so if it fails the board is trash but mine have been ultra reliable and at less than $30 it’s low risk.

The problem is most likely the post processor, when you selected my 1.1e Non-PWM firmware on the original computer it enabled the "Laser D12" option. This firmware and option if for the old boards where pin D12 was used for the laser on and off (no power control). Most boards now use D11 which allows power control via PWM, and D12 is now the Z-home switch.

If you don't enable that post processor option you'll get those connecting lines.

No Grbl does not, it's already to the point on a Nano where OptiBoot is required for it to fit and that's with the buffers being reduced as well. In T2Laser I do multi-pass, tool changes or anything like this within the program using the host PC.

There are alternative boards and interpreters but for low cost diode laser machines the Nano and Grbl are most popular.

I can either create a post processor to strip them out or make it an option to include them in the G-code generation, both would be simple enough. I actually prefer the latter as that was a workaround for some non-standard controllers and should really be handled in a post processor (which I didn't have at the time) so let me add this to my list of updates.

I'm interested in what else you need to add manually, perhaps I could automate that?

It depends on the implementation of G-code, you are correct a G0 does not require a feed rate and most controllers will ignore it and use their max feed rate. It is included for those systems that do not follow the specifications and cause an error if a move command is given without a feed rate specified, perhaps they do not have a machine max rate programmed. Your backplotter should ignore any feed rate associated with a rapid move.

That came out great, well done.

T2 Engraving / Re: Feature request

I haven't but it does sound interesting.

The problem with multi-pass on raster (which is what you need) is the files can get out of hand really fast, to do this I would probably need to save the G-code and run the sender from file which is not ideal for many reasons. Let me look into it but no promises.

That's an odd request ;D

Why are you doing both diagonal and horizontal, I've never heard or needed to do that. Is it to mask a mechanical issue?

I would think the result would be very dark, or do you set feed rate higher - I must try this now.

Disable the DXF Optimizer, the file will load immeditately.

If you have thousands of segments, the optimizer must try billions of combinations so perhaps your computer is running slowly.

Benbox / Re: y-axis not working mostly
« on: September 24, 2019, 07:26:48 AM »
Benbox will only work with their modified Grbl 0.8 so unless you are willing to try newer software you'll be stuck in the dark ages.

T2Laser works with all versions of Grbl, including the Benbox custom version but I recommend my Grbl 1.1e DEFAULT for best performance. It is included with the package and will also work with BCL and other software. T2Laser is free to try, registration (starting at $39.95) is required to unlock it's full potential. If you want a free software option the slightly newer EleksCAM is available and that at least works with Grbl 0.9.

These diodes are primarily used in industrial and commercial display applications (projectors), as the blue source using phosphor illumination as well as automotive LED headlights.

The majority of hobby laser modules (Chinese sourced) use reject product that did not meet the OEM spec for some reason, perhaps it's temperature was too high or it lost excessive output during a burn-in test so reliability is suspect but for whatever reason it was determined as a fail. These are sold at significant discounts for other applications. Endurance purchases new diodes and performs their own testing which is why they are more reliable. There are also some Chinese clone diodes being manufactured now, but the quality and testing is inferior to the Japanese diodes from manufacturers like Nichia.

The difference with the EleksMaker modules is they aren't over driven, so a 6W diode at 5.5W output will last significantly longer. It's still either a Chinese origin diode or a rejected premium source, it has to be as in most cases they are selling the modules for less that or close to the the cost of a new diode.
