Hi Kevon,
Thanks for the reply.
No specific reason , its Just because I have the 17s laying around here.
Weight is no issue.
I like to experiment, even if this means thats ik must create my endplates for the 17s.
If it turns out not to work I will upgrade to the 23s.
Building is fun, even if there are incertaincies I think.

 

Hi there Pete2015

Thanks for the reply. Always nice to hear from someone who is working on a set up that is similar to mine.
As far as I can see the settings are correct. I think (not sure) that $100, $101 and $102 are okay if you set the stepping at 1/16. (Mine is 200.000 at 1/8), but you can always measure the distances to check.

As far as the feed rate ($120, $121, $122): my experience with the machine with Nema17's is that the feedrate mustbe a lot lower, depending on the material that is being cut. Voor (ply-)wood I have these down to 200, for aluminium (but still testing) I turned them down to 120. Take mores time, but it is needed to make a good cut.

Last week my Nema 23's have arrived. I decided to upgrade because of the limited force of the 17's. I will start using the TB 6600 as drivers. And I am also going to put some work in zeroing out the machine. (Limit switches and probing).

If interested I will keep you informed about the progress.

My short-term goals:
- PCB carving (I am using eagle sogtware to generate Gcode for milling and OpenCNCPilot to auto level the circuit board, and I think it is nice to make some PCB boards for the elactronics on the machine; so far I made a powersupply, a power distribution board and I am working on the opto-coupler circuit for the limit switches)
- Good quality aluminium milling. (NEMA 23's needed), I want to cut out the plates for the C-Beam nice and clean.
- Auto zeroing

With kind regards,

Huub

 

So Pete, how are things going with your project?
