You really caught me with this, not only because of the spindle speed control and i love bCNC.
I see a chance to get rid of the ugly knob i have to use for spindle speed.
I understand that your development is quite different from Maslow Firmware and GC, perhaps you still could give me some hints on what files to look at in this post Colaboration request to add spindle speed via g-code in FW/GC.
What has weakened my enthusiasm is, that i can’t just buy a Duo and plug on my TLE5206.
I checked the choice of chip on the suggested PCB and it’s the same as on the Maslow shield.
I have fried 3 of those shields while debugging early releases. It was always the same chip that shorted, the one with left motor and Z together. I saw the TLE as the successor because of separate chips and a higher tolerance for the currents flowing if something goes wrong. I’m wondering if i could use the Prototype Shield with some ‘cross-pin-wiring’ to keep my beloved TLE.
