So I recently upgraded to the Z20 and an 80mm Huanyang spindle. Since doing so, I have not been able to complete a job without the Z axis messing up. During cutting the Z axis will try to retract and fail. This will cause the next z plunge to be deeper than it should be. Alot deeper. Is anyone else …

It was indeed related to EMI. Machine is running much much better now.

Hey Robert, have you adjusted stall homing to reflect the new weight after switching to a spindle? Installing the Z-20 Heavy Duty Z Slider (configuring the software)

I have adjusted the stall settings to reflect the heavier spindle. Machine homes out with no issues. But once again while finishing a 14 hour carve, the machine messed up in the Z axis. Everything worked fine me before upgrading the to the Z20 and spindle. I am at a loss and very disappointed

So I have discovered that the standard max velocity for the Z20 slide is 7m/min as set by the configuration screen. However, 7m/min causes my Z axis motor to stall. At 6m/ min I cannot get it to stall. If I set it to a Buildbotics recommended 80% factor, I am at 4.8m/min. This is 1.8m/min over the s…

Hey Robert, did you try that: [image] Z-20 (Heavy Duty Z-Slider) Additionally when using a heavier milling motor, you can adjust (increase) the ‘drive-current’ and ‘idle-current’ settings the “ Motor → Power " section of motor 3 on the MOTORs page . [image] 349iq2345: Also the Z stepper wi…

I have followed all the proper installation steps. I am on version 1.2.1. I have loaded the configuration file for the Z20 slider upgrade. I have read all this and done all this. But when I jog my Z axis up and down manually, it stalls out and then loses position. I can only assume that when doing a…

I do not feel comfortable increasing the drive current above the 2.8 amps as the motor is only rated for 2.8 amps according to the sticker on the top of the stepper motor. If this repeat carve fails, I will be returning the Z20 slider as well as my spindle. Possibly the entire machine. I am not happ…

Hey Robert, what did support@onefinitycnc.com say to your issue?

The carve is still running and has made it past where it messed up last time. Looks like the velocity change may be the answer. I am sure this is due to the added weight of the spindle. But if the Z20 is sold with an 80mm spindle option, why would I have to slow it down in order to be able to use it…

Oh, and did I mention that it was originally a 14 hour carve and is now well over 21 hours. Doesn’t sound like an upgrade to me

Okay, I have been doing some research and thought possibly EMI could be causing my issue. I have noticed my screen flickering from time to time. I have rerouted some cables and changed the way things were plugged in. I have changed all my settings back to factory settings and am going to try rerunni…
