Maho MH800e Retrofit Project

Do you ini file settings match the requirements for index only homing?

I thought so but obviously something is wrong. I did post my ini file a post or so ago. I was trying to change the direction the axis moves after the index is seen. Nothing I change seems to do anything

Well I had that set to 0 so I figured it would stay at 0 but perhaps I should make it set to be further in the other direction

Hey cooped-up.
Im at a similar stage of retrofit on an MH800w.
Following closely! did you manage to get the machine latched and out of E-stop?
Thanks Paul

Yes I did! I am currently figuring out getting the machine to home properly. Should be getting the touchscreen for the control panel today so maybe I'll have time to work on the interface tomorrow.

I decided to change the velocity it homes at from 1 to 0.1 and that made all the difference. It actually stopped and backed up the the home position. I am guessing that the little stutter I was witnessing was the motor attempting to reverse direction but failing causing it to continue to drift into the hard limit. I then tried that solution on the other axis but the knee decided to go all the way down to the hard stop so I need to figure out how to spin that screw back up off of it. Otherwise i think I have that all sorted. Just need to better figure out the PID tuning and whatnot. I pulled all the relavemt information from the machine constants of the old controller but I don't know if anything other than the max speeds will be relevant.

So can you walk me through getting the machine out of estop.
I have linuxcnc installed on a pc mounted in the machine connected to 7i97t, 7i74,7i84 and a 7i73. 3 heidenhain 602s wired to the 7i97t. just wired +10/-10 signals aswell and Im going through pnc config atmo, tring to figure out soft limit locations and directions for all axis.
