Is it worth it to buy larger stepper drivers?

Category: General LinuxCNC Questions

It should be enough, make the machine work, then it will be much easier for you to decide if you need bigger drives.
Or in short: Move on! :)

Steppers Not Moving / Mapped Wrong

Category: Basic Configuration

1. check the ini file what the value of step space and step time is, make them all 5000 if not already
2. i would wire the drives to Mesa as single ended, you have them differential (might be just below the opto threshold)
3. do not wire the Enable on the drives at all
4. do the motors lock when the drives are powered?

I stripped a redbox machine to use parts for my cnc plasma table. It came with a nice little heater I am going to incorporate for just this.

Okay that makes sense for the tandem axis.

okay my mission now is solely to get either the X or Z axis jogging.

I am running gmoccappy and tried to look in Halshow for any watchdog but was unable to find anything that looked like it would be an axis watchdog, where is that located in Halshow?

For the drives i am using tb6600 with all the micro stepping turned off. The lead screws are 10mm with 2mm pitch so that makes each axis scale 2540.

I also double checked the wiring from motor to driver and driver to board. For the X axis the driver to mesa is below:
Dir+ - > 0Dir+
Dir- -> 0Dir-
Pul+ -> 0Step+
Pul- -> 0Step-

It seems idx is not incremental reading this 
linuxcnc-ethercat.github.io/linuxcnc-ethercat/el7041.html

i think i wrote this driver or driver variants myself, years ago.
Could be outdated now. This for your info.

updating the linuxcnc-ethercat is good idea.

codeberg.org/skynet/linuxcnc/src/branch/...er/cmake/libethercat

you know how cmake install works?
There is also a build script in the repositoy.
Otherwise you can use the linuxcnc install method.

Is it worth it to buy larger stepper drivers?

Category: General LinuxCNC Questions

I need 2 stepper drivers to drive two 4.6A stepper motors.

The DM556 driver is optimal, but only provides 5.6A peak (about 4A RMS)

Is 4A enough for a 4.6A motor?

I currently have one DM556 driving another 4.6A stepper motor (I have 3 identical motors for a XYZ CNC router), and it seems OK.

Is there a major downside to reduced current?

moog animatics smart motor - need contract help to configure

Category: General LinuxCNC Questions

I have built 3 fully functional cnc routers using Moog animatics motors. I use the Ethernet Smooth Stepper with the break out board for the heart of the router. SM3420 and SM43165 closed loop servo motors for the axis. Two of the routers are 2 foot by 2 foot by 16 inches in the Z axis. The other one is 4 foot by 4 foot by 12 inches in the Z axis. I used Mach4 for the user interface. Works great. They are about 3 years old now and all are still running great. One has about 5000 hours of run time now. Ground bounce was the worse issue. I made an in-line, plug compatible PCB to isolate the motors from the controller board. Animatic’s design has the motor power and the logic power connected. With a 5 volt step/direction signal, it doesn’t take much. High speed optical coupler works great.

A Axis creeping - Bias not fixing it - axis not responding to jog buttons

Category: General LinuxCNC Questions

I'm seeing the DRO move with the creeping (that's how I identified the creep), I disconnect the analog output to the drive and it stops, I'm measuring 10mv about on the output to the drive, so the creep is being generated by the control. I tried switching the Encoder direction, no change.

I think that as long as it gets fed with fresh (moisturized air) it will be saturated too quickly. Probably it's better to put it in a cabinet where the temperature is higher. The higher the temperature the less moisture it contains.
Besides that I think it's more likely that it's failing capacitors. In general industrial computers are more resistant to low temperatures.

Good catch. Thanks!! Forgot to fix on the copy and paste. Now if I can figure out the "Joint 0 amplifier fault" messages.

Hi,

in the xml file. Idx=5 for all slaves.
Thinking should this be a incremental value?
