Have the highly common drivers typical on Fiber Galvo systems for Z and Rotary. This JPT-C-80 form JCZ. The rotary is energized, yes , both coils about 1.2ohm good… but no commanded movement. In the Lightburn window Rotary Set Up, where Rotary is ENABLED there is a Test button at the bottom. When I press it, nothing happens, it stays blue` and nothing is reported below it. The rotary unit/function is new/unused/unapplied. What is the next step in troubleshooting ? Of course, Laser Everything and every ones similiar videos Ive watched. Can I actually see the Lightburn “signalling” the motor, measure that electrically?
Nope… The motor driver for the rotary is in the case…
Without going into the case and probably voiding what warranty you do have, I’d suggest you contact whomever you purchased it from…
There is always the possibility that the it’s wired to plug incorrectly, but again, that should be a vendor issue…
Usually it’s a two phase motor, if a leg of each phase is connected wrong, it won’t move, since there will be no current flow.
What do you have for steps/rotation?
Usually a Z axes is a EZCad3 option… ?
Good luck
The LB rotary function is running my z-axis. My JCZ JPT C 80 fiber came with Ez2, programmable Z, and Rotary and all that worked…I have another question into the software forum about the Z issue, can I just swap the cables, and of course change the settings on the driver as appropriate?
I think you’re ahead of most of us with a Z axes. As far as I knew the board that operates with an additional Z axes, with a rotary was only supported with EZCad3…
Don’t have windows, so I’ve never used any of the ezcad software laser software, except the to correct for lens distortion… So I won’t be of much help.
See if @Rick might know something that can be of benefit.
Good luck
Following along.
Interesting setup. Are you 100% sure both the motorized Z and the rotary were both working correctly with ezcad 2 and no other software?
,As noted above unusual to have programable Z drive on ezcad2, didn’t know it was even supported. Pretty sure it is unsupported in LB.
I have programmable motorized Z on LB but use a separate CNC controller and UGS software.
PS
If you decide to disconnect the Z column and plug in the rotary, do not hot swap, bad for the microstep driver.
Appreciate your time ! Yes, its a JCZ unit, JPT-C-80-M7 Fiber 1.064. #1) Sold with programmable Z (do not have electrical buttons for Up/Down) and rotary. Their LMCV4 board Com4 has two motor driver out pin outs (4 wires). One is their Z the other the Rotary. Yes, ran fine. #2) Lightburn answered me with little concern for what they called “automation”, and no, not supported in the Galvo package. I do not understand that, we need focus control WITHIN the program run structure.
The EZ2Lite has a single Control Board FBL1-B-LV4 out for rotary. The regular std. Control Board LMCV4 has ability for two. However, the output is set for extension axes X and Y (so designated on print) to Z and Rotary respectively. Lightburn for Rotary wants to use the X control board output (pins 6,7,14,15) … so… simple switcheroo. in the chassis at the signal input. Tested and fine.

Very interesting, thanks for the update and explanation. I was not at all familiar with that set-up. How do you control the motorized Z?
there is a switch on the side off my chinnese laser wich i need to turn on to use the rotary tool,then swich back of again when go back to table,im not sure i have not used the rotary yet i just know i need to switch it on.on the side off machine.but i would assume you press escape and you can higher and lower the laser.
this was my first motorized Z controller, analog
Latest one is CNC, a lot nicer. 2 drivers, control an X axis table with it as well.
