Problem…I just bench tested, set up, and calibrated a 50:1 Chinese 4th axis rotary. Worked perfectly and was repeatable and accurate. I am using a JST 4 pin connector/pigtails as I have seen/heard others do in leu of a flat ribbon setup. When I permanently ran the wiring, I plugged the connector into the SLB upside down. This threw an alarm on the rotary driver and on the SLB. I turned everything off, flipped the connector over, and turned the SLB back on. No alarms or other red lights. Gsender in idle. When the machine tried to home, nothing would move for maybe 30 seconds then alarm homing fail. I have unplugged, restarts and nothing will move. Now when homing, the blue light is on the SLB but won’t stop the homing cycle. Pressing stop or hitting Estop does nothing and is stuck in homing mode until I physically turn off the SLB. Even if I try to jog, the status light on the slb goes green but no movement. I don’t see any mysterious changes to the firmware, if that is even possible. I’m kinda perplexed at this point and hopefully didn’t let the smoke out. Any suggestions would be appreciated.
I was wondering, readi g your story. Do you still have the rotary connected to the slb or are you testing movement of the cnc without the now maybe faulty unit?
Have you established minimal working conditions for the slb to try and undo the errors? Reinstall gsender or side install an edge version or even try movement by a 3th party software like ugs or lightburn?
Disclaimer: I do not own an altmill, rotary, nor do I use a modern version of gsender (never used edge either). I would however Disconnect first and see what that does before stripping down the slb and reinstall gsender or try alternative software.
I disconnected everything, checked all wire connections and voltage at pins. 24v at main terminals. No signal voltage at any axis pins when attempting jog movement. Light turns from white to green and status bar changes from IDLE to JOGGING as per normal when attempting to jog…no movement. Z axis wont hold torque anymore but set to do so in firmware. No 24v at PWR1 nor PWR2 where power was previously. Rotary was disconnected from SLB, connected to an independent speed controller (same independent driver and power supply), and it works fine, holds torque when energized. Jogging A+/- behaves the same, however, 4.5-5v at pins. Odd, but I don’t know enough yet to say otherwise. Are there any firmware settings that aren’t “visible” in the Config that could have changed when the alarm/fault happened? I suppose I could re-install Gsender once again. Are all the settings stored in Gsender or on the SLB? I’m sure there’s a way to save or backup my settings so I will look into that. Firmware reflash? I don’t know and may have to reach out to support for some guidance.
Side note, I removed the SLB from the aluminum enclosure and inspected it under lighted magnification. Not a “poop stain” or irregularity anywhere, rather, a very clean and well made board, for sure!
Sounds like your uP is oke and you blew out something at the driver psu. I have no time to dive into the scematics rn but if you search for schematics in forum, posts will come up with a link to them. (Posted them a few times myself too) maybe those can give you a hold on finding where to poke your board.
