Stuff you will need issues

[loeschr]

In the project wiki, the list of stuff you need has bad links. The servo/stepper hybrid motor and the motor driver are dead links. Could you either post updated links or enough specs on both so I can source them?

Here is a link to Automation Technology product page for the exact same one that is in Jame's vids: https://www.automationtechnologiesinc.com/products-page/hybrid-servo-system/hybrid-servo-drive-kl-5080h/

Also, here is the copypasta of specs for future reference: NEMA 23 Hybrid Servo kit (closed-loop stepper system): one Hybrid Servo Driver KL-5080H, one NEMA23 KL-23-2N-1000 Hybrid Servo Motor with one Encoder 1000 line

A: KL-5080H, 3-phase Hybrid Servo Driver for NEMA23 Hybrid Servo Motor 20-50V, 8.0A Peak, No Tuning, Nulls loss of Synchronization Closed-loop, eliminates loss of synchronization Broader operating range – higher torque and higher speed Reduced motor heating and more efficient Smooth motion and super-low motor noise Do not need a high torque margin No Tuning and always stable Fast response, no delay and almost no settle time High torque at starting and low speed, high stiffness at standstill Lower cost B: NEMA23 Hybrid Servo Motor, KL23-2N-1000, 1/4" shaft Rated Torque 282 oz-in, 2 N-m, with one Encoder 1000 line

I haven't been able to make a serial connection to the driver. Some older forums posts I read suggest they have prevented it from working for some reason. They've told me in an email that I shouldn't have to make a serial connection and that it was set correctly already. It is working for me however I have to set the Stepper_Microsteps to 8 in the code. I'm using 2:1 pulley reduction (72-tooth on lead screw and 36-tooth on the motor) and would have expected to set the microsteps to 2 based on your notes in the code. I've successfully cut 1/4-20 thread and it's accurate so it's working. Just not sure if that is expected.

Does this seem correct James?

Sorry for the broken links. The link I provided is to the Automation Technology eBay listing, which saves a couple of dollars on shipping. Not sure why they changed it, but I put the new link in the wiki page.

I had no trouble connecting to the serial port on the driver using the 64-bit software linked on the data cable page on the Automation Technology web site here: https://www.automationtechnologiesinc.com/products-page/nema23-closed-loop-stepper-motor-system-hybrid-servo-kit/calibration-cabel/

If I remember correctly, the driver comes factory-set to 1000 steps per revolution. I have a 3:1 belt drive to the leadscrew, so I have my steps set to 1000 and my microsteps set to 3.

If your ratio is weird, you need to determine if it's your encoder settings or your stepper settings. If the RPM display is correct, your encoder is set up correctly. If not, start there.

On the stepper side, if the numbers look right, but you're getting the wrong ratio, check any other gearing that might be in the loop. On the Grizzly G0602, there is a stock gearbox with a couple of knobs that can also change the ratio. I think setting them to A and 1 results in 1:1 gearing. Set the knobs, mark the leadscrew with a sharpie and turn by hand to be sure.

James: Can you give me a good source for the gears and belts?? I have accumulated all/most of the parts and am about ready to start 'breadboard' assembly and testing.

I'm also looking for specs of that enclosure. Couldn't find it on the wiki at the first glance.

I found a great (and inexpensive) source for just about any kind of pulley you need. Check out https://us.misumi-ec.com/ You pick the style and then can configure the size, number of teeth, shaft dia, key or set screw, etc. It takes about a week or so because they are made to order. I got all my pulleys for this project from them.

This is great to hear. Can you share a rough pricing with us for comparison sake?

They only trade with company not private
