I am using this topic to share experience on all stepper motors: open loop, closed loop etc.

Hi,

Do you have a mounting bracket for this kind of square sensor? such likes this image:

Ground Ballscrews

Do the Ground ballscrews actually meet C5 accuracy? Hard to imagine given the price, but I'm curious if anyone has any experience. Also curious if anyone has any experience with the double nuts for sale here. Just chasing the last little bit of backlash in a ball screw assembly.

Thanks,

Lewis

2040 Actuator Kits

yaning — Tue, 03 Mar 2026 15:47:28 +0000

I am working on building a fixture for mechanical testing with gantry/CNC type of control, and looking at the following actuator kits:

"2040 V Actuator Kit": https://diycnc.ca/product/3d-printer-motion-control-kit-for-x-y-axis-2040-v-slot/
"2040 H Actuator Kit": https://diycnc.ca/product/2040-actuator-motion-control-kit-horizontal/

I had a few questions about them:

What model of stepper motor comes with the kits? Are there any speed/torque curves for these, or any max speed/min accuracy specs for the motion system as a whole?
Are the “V” and “H” type of kits the same as each other, just differing in the orientation of how the plates are mounted with respect to the v-slot? How should I think about choosing one orientation vs the other, e.g. is one more suitable for certain kinds of loads/motions/axis of motion?
Are there CAD files for the mounting frames for the stepper motors? (Everything else is more standard and I can find elsewhere online)
I am looking to get ~50cm long pieces, but was a little unsure how the order page for the “H” kit works — do we enter the length in cm as the qty? In that case, the price comes out to $8.50, which doesn’t seem realistic, given the “V” kit is $35 for the 0-50cm length. Is that expected?

What is the longest section of 2080 V Slot Aluminum Extrusion you are able to ship?
What is your estimated timeline for delivery?

Confused with the stepper motor drivers

JeffZ — Sun, 01 Mar 2026 01:05:33 +0000

Hi, these motor drivers are very confusing to me. I asked AI, but it sounds like it doesn't know too much either... do you guys have more pictures of these? I am looking for a DM556, or M556D, or something similar.
