Hm, not sure about this one. stepgen.position-cmd is the target position: where it wants to be at the end of the current move; stepgen.position-fb is the current position. While in transit the two will differ, while at rest the will be the same. I don't know enough about the motion controller in emc2 to say why this is happening. What's your stepgen.maxaccel and stepgen.maxvel? They both default to 1.0, which is probably pretty low. Oh wait I saw in your INI file below that you upped them to maxvel=10 and maxaccel=100. > 3.

In TRUNK the hm2 stepgen uses u32 params for the waveform timing and the manpage reflects this; in 2.2 the hm2 stepgen uses floats and the manpage reflects this.

There was the pwmgen scale fix on 9-11, since then the only new thing is support for the 4i65 PC/104-Plus board, which I dont think you care about. > 5. HAL & INI is at: > http://pastebin.com/m36daceed Wow, 40K steps/inch?! Your HELP_FILE disagrees with your DISPLAY (but maybe that's ok, I dont know). Shouldnt your HAL file use variables from the INI file? (I've never written an emc2 ini file so I dont know.) -- Sebastian Kuzminsky Theo: "Julian? I haven't seen you in twenty years. You look good.
