Funny how that works out. I originally built mine to make clock parts and now I just make R/C parts. Never have made a clock gear with it. Maybe this winter.

I am not aware of a low cost foam cutting software that will do that.

I know this is not related but it is a good deal.

I just saw this tracksaw system for sale on Amazon for $100 and ordered one.

Sorry for highjacking this thread but I saw that you used the HobbyCNC Pro controller with the HobbyCNC steppers. Im currently in the late stages of building my own milling machine. Are now connecting the steppers and testing but I have some kind of problem. Hopefully somewhere here have earlier had the same problems and have solved them hopefully. My questions are:

1) The steppers are the 23-305-DS8A and I have connected them according tothe instruction in the end of the HobbyCNC pro controller instruction. Can I use a 5 wire cable and connect all COM cables to the same pole or do I need to separate the A, a COM and the b, B COM?
I have good 5 wired 0,75 cables that I want to use if possible.

2) to try to search for a fault I connected a loos motor (Same model and brand) to the controller card and the motor just stopped and if I try to jog it it takes a small jump forward and then frezes while giving away a squeeeeling sound. What can be wrong??

3) Any special setup that one need to do in MACH3 (except the pin configuration for step/dir for each axis?

Hobbycnc has a support forum that can answer these questions better than I can. Here goes my answers.

1. I don't know I usually hook things up the way they recommend in the instructions.

2. If the motor LOCK UP when powered on then it is probably a software issue. If you can spin the shaft by hand while under power then there is a problem with the controller.

3. There is a setup video available of the machsupport.com site.

Thanks for posting all of this - threads like these remind me that one of the purposes of the internet is the democratization of information. Philosophy aside...

Have you ever cut Corian with your Hobbycnc setup?

Your welcome.

I have cut Corian. It cuts very similar to MDF.

If you would like to see some of my other CNC stuff, check out my blog.

Edge Finder, Z Zero plate

I thought some of you might find it useful to see how I locate the edge of a workpiece prior to machining with the CNC Router.

I use a Makers Guide Triple Edge Finder to automatically locate the parts Z height, and corners. I use a free plugin for Mach3 to do the movement.

I recently did some more upgrading to my CNC Router table. I decided to do an aluminum CNC Router build. I made some parts from machined aluminum to replace the MDF Parts.

The upgrade went great and have a stronger, faster machine.

There are more details on my blogs.
