Gerry - good morning and thank you for the reply.

You are right, 16 IPM is slow -- remember tho, I was cutting at 6 IPM (lol).

I'll try the 8 (or less?) accel. That setting doesn't seem to...

Doorknob, et al - I changed the wiring per your description for all three motors. The speed gain seems to be about 2X. The motors seem to run smoother. I don't know if that's due to the...

Gerry - Thank you - I appreciate you sharing your perspective. I originally did exactly what you said -- cheap everything (the entire system including a used PC was less than $800). The original...

OK -- yeah -- me too.

Jest -- Thank you so much for your response. I guess I should have asked what size motors for X and Y and how many starts on that Ballscrew you're using. Thanks again.

Widgitmaster - thank you for your feedback. Most helpful and I do see how the 3-start, 10-TPI 1/2" diameter screw would move 1/2" per rev. And, you've now actually answered my question about if the...

Doorknob - Thank you for the clarification. I will try the half-coil configuration you suggested and report back.

Thank you also for the clarification on the series vs parallel hookup. Is...

Jest - thank you for the info. What kind of rod/nut are you using? I presume those IPM measurements are rapids? Do you remember your wire configuration with the TB6550?

This is how the motors are wired to the the 6550: White & Yellow are open. Black XB-, Green XB+, Blue XA+, Red XA-. I don't know if this is a full or half coil hookup. I followed the diagram...

Doorknob - Thank you for the suggestion. You are correct - four wires connected to the drivers and two taped off. I don't remember off hand how I wired the motors (half vs. full). I do remember...

Thank you for the reply Widgitmaster. Well then maybe I don't understand your explanation of the 3-start rod. If a 2 start rod has a 2:1 ratio, why does a 3 start rod have a 5:1 ratio?

Widgitmaster: Thank you for the fast reply.

I understand your explanation of the 3-start screw. Thank you for that. I'm curious how you determined that going to a 3 start screw would give me...

I have a home built 2'x4' machine I did on the very cheap. Machine works for my purposes (for now), but I would like the machine to cut faster. At the moment, I'm only cutting mostly PVC boards and...

Where in Florida?

I've had no luck with Wantai. Same story - one motor went bad after less than six months. They state 1 year warranty. I contacted them for return and exchange. They kept telling me to wire...

I see this is an older thread, but I had this same problem.

I used "Windows Update" to correctly install the .NET framework. It took several iterations and restarts, but eventually got it to...

It's been a long time since I've had access to an O'scope or logic probes (I know I'm dating myself).

Anyway, I did some additional experimenting with the cable numbers and I now have all three...

I don't have a picture. If I put the Pin # for the Z-axis in Mach3 onto the pins for the X-axis, the motion for the X-axis shows up on the motor connected to the output for the Z-axis on the driver...

I did some experimenting setting the Mach3 pins to different combinations.

Only one motor is turning when it's supposed to. The second motor makes noise when it's supposed to be turning and the...

I will try your settings.

I should note that I am getting some buzzing in the +Y direction, but no movement. Absolutely nothing in the Z. The screens for the X, Y, and Z on the board for the...

Mach3 Pin/Ports as follows:

-------Step-----Dir---Step Port--Dir Port
X-------5--------6------1----------1
Y-------2--------1------1----------1
Z-------3--------4------1----------1

Enable 1,...

Good afternoon. Great thread, thank you to all the contributors.

I'm a rookie building my first 3-axis CNC. This is my first time posting. I have no experience with CNC at all. I do have some...
