Thanks, overall I am pretty happy with how it turned out and the performance. I have been meaning to do an update but I have been to lazy so thanks for the motivation.

As far as the PC case it...

Couple of questions concerning programming.

1. I am wondering if there is anyway to record the expected vs actual coordinates after homing into a log file? I would like to keep record everytime...

570oz in motors from AutomationTechnology, screws are RM2010 from Linearmotionbearings2008, and PSU is 60V.

Getting close to being finished. Even though I haven't posted in a long time.

After getting some quotes from machine shops to make some aluminum plates for me, I decided to make them out of...

Been working more on the electronics and making some major headway. Last night function tested all of the motor connections, inputs, and outputs and everything seemed to work. Just waiting for a...

First shipment of electronics arrived. Just missing the drivers, motor cable, and other bit and pieces from eBay.

Motors, BOB, smoothstepper, motor connectors and limit switches.

Been working on the electronic cabinet. I think the $20 computer case is quite a find. Got the control computer mounted in the case and most of the power cables lengthened. Just waiting on a few SATA...

The main propose for this machine will be manufacturing kitchen cabinets. That require routing as well as drilling. Instead of changing bits we are going with dual spindle. The g-code should be...

Anybody have an answer to this?

Wondering how you can add voltage control to a toroidal PSU like a KL-6020? I know you can remove coils but I am hoping to basically add a dial to reduce the voltage by up to 20V.

I am wondering...

Yes for the G540. but I am still planning on using G203V so both are well below the 80V maximum. So with that in mind with a motor that has a 3V rating with 2.5mH +/- 20% would you say play it safe...

Another question for sizing PSU's. I noticed that the voltage output of a torrodial psu drops as more current is drawn from it. My question is when you use that formula to calculate voltage...

Ahh I thought you meant the Z axis. The X axis are supported rails as well as the Y-axis both have that sideways orientation. I played around quite a bit with the ride on orientation but couple...

First off thanks for all the advice. Alot to process. mcArch varying the distance between z's is not a big concern for me as it will be for routering and drilling but down the road if I see the need...

What is everyone's thoughts on running 570 ozin 5 amp on the x and y and 381 ozin 3.5 a on the z axis?

Both have inductances of about 2.5 mH which works out to about 48V. Total of 2/3(23 amps)=...

I think I am starting to buy in. This is the torque chart I was looking at for the 1200ozin and I just noticed that the driving voltage is 100VAC which might account for what everyone is saying about...

Thanks for the reply. I am trying to pullout the advice from your comment. As far as the spindle router debate at this point I think I will start slow and work up until I feel like the router is...

Feedback welcome!

I have heard that bigger is slower. But I also have heard if you don't have enough torque you will lose steps which isn't good either. What makes the NEMA 23's so much faster? Is it just inertia or...

I have read that bigger doesn't mean better but i wanted to make sure I have enough torque available as I don't want to be losing steps. What makes them faster? Would I see a big speed difference...

Hello all,

After spending quite a few hours lurking and researching CNC routers decided to take the plunge and start building my own. I have been working on the design for a couple of weeks and...
