Spindle Gear changing

Category: General LinuxCNC Questions

I have a similar (but different) system on my lathe. Mine has a 2-speed gearbox with magnetic clutches to change gear. (The differencce here is that mine _can_ change gear at zero speed)

I have a HAL component that controls this, and actually does rev-matching (ie, it will shift when the ratio of the shaft speeds matches the gear ratio)



Gearchoice.comp is here: github.com/andypugh/HalComps

This looks very odd. It looks like a gmoccapy glitch, but can you try the same sequence in:
1) The gmoccapy lathe sim config
2) The axis lathe sim config
And see if you see the same behaviour?

The problem was related to the Ethernet settings. It was solved.

Yes. but do not wire EN, on most of these types of drives EN is not Enable, it is Disable, so sending signal to EN will actually disable the drive.

Hello everyone,
I wanted to connect my NVEM V5 RT1052 with this DRIVER (just to test the outputs not for daily work). I am not very expert and I do not know how to connect this type of connections, in the NVEM manual there is no this type of driver.
 
 

I think but I'm not sure if it goes like this:

EN- <----------------------> ????????

I was able to test the debian 13 image with cia402 ethercat drivers, i can home the machine but after a few jog movements i got following errors and couldn't move the machine until i restart linuxcnc, latency is the same as my config that can runs in LinuxCNC 2.9.4. the only time i was able to run a gcode it only made the first g0 movement.it shows all the time wired connection loss, the only wired connection is to the ethercat drivers. i can run the same machine on the same pc only booting in LinuxCNC 2.9.4. without any erros, so its not a hardware problem.

Yeah... there is no contact with the ECL16DP. Only with the S1-M20.
What can you do? Power + ethernet connection. Maybe you can connect only the ECL16DP? Use the ETH0 port.
That new xml looks to be the same, except for the imagedata that looks intimidating. But it's just the bitmap of a picture that TwinCAT uses to display with the unit.

Hello,
I am installing ethercat but the communication light with the drivers is not flashing and it is not communicating with the drivers.

Well... that's certainly a unique machine.

And a good demonstration why 40ipm is a realistic top speed.

Today I reproduced the problem again. When running code with
G96
(constant surface speed), if I stop the spindle and then start it again, the spindle runs at 40–60% lower RPM than expected.If I resume the program at that point, the cutting feed does not adjust to the reduced spindle speed, which can be dangerous. After that, I stop the program, and Gmoccapy looks like it does in the attached screenshot.
 
 Then, if I reload the program and start it from the beginning, the machine suddenly runs at a crazy high speed, and the graphical interface also shows the actual (high) speed.

Spindle Gear changing was created by dctrytsman

Spindle Gear changing

Category: General LinuxCNC Questions

Can someone please explain how to set up gear changes. My lathe spindle motor is connected to a gearbox that has two gear ratios and the gears are changed by a pneumatic actuator. The gearbox is then connected to the spindle via belts. The spindle has a encoder connected to it via a 1:1 geared belt drive. The feedback part of the system works fine.

How can I connect this to HAL so that the machine automatically selects the correct gear based on the requested spindle speed. I think that the gear change should take place when the spindle speed is very low, but not standing still as the gears wont change smoothly.
