I finally updated the host to the newest version (1.0.5, I hope), and also found that numerical positioning is gone. This usually isn't a problem, but with a few multi-part prints, I've been lining them up manually based on relations between certain features and the part origin. For example, an interlocking planetary gear system: I could swap out any of the planets individually without exportinby cfrpCopy - Repetier
Well, to close this out, the solution was connecting the DC ground to the mains ground. Thanks for the tip about measuring the voltages, I checked between the +12v DC to mains ground; the ATX supply read 12v, while the dedicated read as an open circuit. I'll update if anything goes wrong. Like a fire. Sadly, I think I broke the USB-power mode on my RUMBA board in the process of trying to get tby cfrpCopy - Controllers
Dedicated PSU has the power cable going into the terminals as they are labeled. Green into ground (symbol), white into "N", black into "L". I have heard of the problem in other situations, I suppose i should have recognized it. I remember using a 3-prong to 2-prong converter being a solution, but that didn't help (i just disconnected the ground at the supply end). The RUMBA now resets when i pby cfrpCopy - Controllers
I was using using an ATX PSU (500W) with my RUMBA for a while now, but I just replaced it (because it liked to shut off in the middle of prints, and the 1A load on the 5v trick didn't work) with a dedicated 12v 30amp power supply. I have everything wired up, and I can get the board to turn on with the new supply, except USB communications doesn't work. Thought I burned something out, but when Iby cfrpCopy - Controllers

Well, EXTRUDE_MAXLENGTH solves the mystery of the conspicuously round number. But I’m not sure how to try quantifying the problem. Usually I get it just by hitting extrude and retract a bunch in manual control. I don't have the same issue with the XYZ moves (although when the extruder stops responding to commands, so does everything else - it sort of queues up the commands). I’ve got the DRV88by cfrpCopy - Repetier

I have this same problem (only when using extrude in manual control) with the both the .95 and .90 host, and the .90 development firmware. Hardware is a RUMBA board in a delta configuration. I don't have an LCD, so i can't see the buffer fill up, but if there's anything i can output as a diagnostic, i'll get that.by cfrpCopy - Repetier
Ok, Fixed. You are right about the offsets, i was using the "defaults" for testing, that doesn't make a difference. I was also using EEPROM_MODE 0. Apparently Z-probing values don't get copied correctly without using EEPROM. Easy fix. I'm not sure if I'd consider it a bug, or if it needs to be this way to maintain leveling data when the board is powered off. EDIT: Thanks!by cfrpCopy - Repetier
I'm trying to set up Z-probing/bed leveling on a delta printer, and I'm having a bit of an issue: when i give the G30 command, the head zips down at what I think is full speed (it's more than either the move speed in the host or my normal homing speed), triggers the probe, and returns to the start point at full speed. It returns the following 3 lines: Warning:Invalid delta coordinate - movby cfrpCopy - Repetier
