Handy Cam tool for cutting timing pulleys was created by mariusl
I found this software for cutting timing pulleys that I thought was very handy. It is only a couple of dollars but worth it. The guy who writes it, Bob Adamns, made special changes, on request, to be Linuxcnc compatible.
You can find it here. www.cad2gcode.com/pulley/
I am not affiliated with this software or Bob in any way. I just found it to be handy and wanted to share with all.

Certainly cheaper than buying the right cutter and doing it "properly"
However, now that I do have the cutter, I am happy to tooth any supplied blanks for LinuxCNC users, for free

That's very impressive Andy. I wish we all had such fancy machines as that but for the plebs, we have to make other plans. The software allows you to use the blade type gear cutter that is shaped correctly or the right size tool with a second pass to bevel the teeth. It is actually just an indexer program, the rest is up to the user.
May I ask what the hobb cutter cost you?

Looks like you have the Harrison up and running.
Still seems to have a 'hand-draulic' X axis, or is it manual or CNC as suits?

I think I paid £32.
The same guy has several others, but I don't recognise the belt profile on many of them.

For example.

The pulley I am making there was for driving the X axis, so I was having to drive it manually.
I will have the choice of auto or manual on all axes when I have finished (which isn't far away, might even be today)

That is very reasonable. I looked his stuff but that was the only 5mm pitch hob. The others are all 8mm or some other funny pitch.

Hurrah! This is the pulley that I am making in the video in-use:

Have you got a big motor on the knee or just high gearing?
Because my spindle is not fixed, I left my knee on the manual handle and move the table up to the spindle to touch off as required.

They all have pretty much the same gearing too, about 4:1. I think that the machine could probably run faster but I am hitting the limitations of software commutation.
(And, anyway, this is a Universal machine so I need a motorised knee when using the horizontal spindle)

I suspect that motorising a quill is somewhat easier than a knee, but there was no choice here.Because my spindle is not fixed, I left my knee on the manual handle and move the table up to the spindle to touch off as required.
