Wabeco CC-F1210 LinuxCNC conversion

This is HUGELY valuable information! Thanks for the input

Looking at the main board with 3 drive lines and one direction line in combination with an HSE dongle that I found with an Atmel inside it is no wonder that people had such horrifying performance with the factory software on these units. Running everything though an Atmel with only one direction line is seriously tying the shoelaces together of the poor machine. Really crazy that software/hardware developers thought that is the most sensible way to protect the whole lot. It might be worth while to reverse engineer the dongle, but seeing how bain dead it works, I'm just dumping the whole lot, switching to the TD6600 drivers with a 36V switch mode power supply and powering the whole train through LinuxCNC.

The 4 TD6600 clones arrived. I have a Dell Lattitude E6230 with a dedicated parallel port on the dock connector and with an original dock with parport the unit is working without limit switches. The latency of this laptop is surprisingly low.  Microstepping is set to 400 that gives me 500 steps per mm on the 30:12 reduction on the belt drives and a spindle pitch of 4mm. The backlash on my DRO is only 0.03mm for the X and Y axes. Now it is time to add limit switches, I guess.

If I repeatedly measure the backlash, can one set it somewhere in the software per axis?
