OK - Here is where I’m at, We got to the point of hooking up the encoder to see what we would get and things got funky and had to check our breadboarding. Ran out of time. I’ve now made a shield with the Eprom and a motor connector to move forward with testing. When I connect I get a GRBL 1.1f msg. From a terminal I can run commands and get replies “$$” or “$X”. We can spin the motors. However if I connect to Ground Control it constantly drops the serial connection. Are you intending to use Ground Control with this firmware?

I’ve got several level converters if you want to try one.

IIRC, Ground Control looks for GRBL 1.0, so the 1.1 may be confusing it.
The intent is to be able to use any grbl compatible g-code sender
I downloaded files off git hub and sent them to Chinese PCB board and assembly manufacturer. Cost of the assembled board is around $13 and cost of the Chinese Ardinio Due is around $13 as well. I will sell on market place when I get them in about two weeks. By the time I add shipping from china and shipping to final destination I expect the price to be around $30 to $40.
One would basically replace their existing electronics with this unit.
Not looking to make a profit, just looking to get this new board out into the community so the maslow can further be improved.
Also, will this eventually work with Mach3? I have a shapeoko2 (still in the box ) that is planned for the workshop, as well as a CNC mod to a grizzly 7x15 lathe. It would be great if I could control all three with Mach 3 (I am planning to have a parallel port switch and separate profiles for the SO2 and lathe to be able to run off Mach3)
To be fair. the number of shields that have unsoldered themself or died during chain wrap, firm- software bug and to many 30kg ‘pull tight’ in calibration must be a low % of the total shields sold. It should work.
It perhaps just personal because i fried 3 shields and it’s hard to move from the TLE if current protection is not added here. I would sign up and pay for testing if you ship to my remote location
I think I understand what you are talking about now. I"ve been talking to the creator and sent him tle5260 board, his initial impressions was he doesn’t think it will work with tle5260 motor controllers.
Ok… that makes sense. Where is the github repo you referred to? It’s not @ldocull’s repo is it (I didn’t see something like that there)?
As for TLE5206 boards, I could be wrong but I think most everything can be addressed in software… I think you need to just address how the pwm pulses are generated (the two chips do it differently) and gpio for the board-type detection.
someone would have to sit down and do all the work of implementing the servo
control loop and maslow kinematics into Mach3, getting this done for GRBL
probably doesn’t help much.
