I am currently facing a similar issue as contacttod. I was previously using a gshield v5 on the OX CNC and decided to upgrade it with a tinyg. My motors are 1.8 degrees Nema 23 and were working perfect with 8 microsteps and the tr rate was set to 26.772 on the gshield. However, once i connected the tinyg i noticed if i enter 10mm it would go a lot more than 10. Then I decided to use a calculator online to fine tune the tr settings and it turned out that if i reduce the tr the machine travels even more than before. If i increase the tr rate then it goes lesser. Eg : X10 goes 100mm on 26.772 tr and X10 goes 10mm on 59.86 tr.
After i made these adjustments my machine jog speed has become a lot slower and if Im correct if the machine travels more than the command given a reduction in the tr rate corrects it. But currently its the opposite. A increase in the tr rate is correcting it.
My X Axis is connected to motor 4, Z Axis to Motor 3 and both Y Axis to Motor 2.
