It's that way in LinuxCNC too. And those work. But the psng screen for the touch probe and other code done by users looks at the length of the tool. If it's zero it uses the tool setter since it may be a drill bit in a Jacobs Chuck or some sort of R8 tool instead of a TTS holder.

Yes. I think I must have a hard coded parameter somewhere. The tool lengths entered manually into the tool table appear to work although I'm still finding even there about 0.005" gap to the 1-2-3 block. That could also be a backlash issue with the acme screw and bevel gears so I'm not...

I'm about to quit metal working forever... For the life of me I cannot get this tool measurement stuff working. I've measured my tool setter. I've measured tools. And my probe appears to measure correctly. And yet when I measure a tool and move it 1" above the probed work piece it's off by...

In order to keep up with @David I've finally after many years bolted down my Tool Setter. It's now permanently at X0.5 and Y6.5. Of course the Y value assumes I haven't cranked the head way out. And since I bent the tip of my touch probe (also now a while ago) I thought I'd go through and...

I think I'd better stop here...

I wasn't actually talking about the tool holder...

I found the Weldon works well with PLA. Now I wish I could find my tube of it. It's gone walkabout. Might have to buy a new tube just to be able to quickly find the old one.

Spelling... Calcool and talking about 'us'. Hence Calcoolus...

Let's take a quick look at what is happening under the covers or if you didn't have a button on the screen to measure a tool length and place it into a tool table. G-Code for CNC expects to have a co-ordinate system defined. When we refer to machine co-ordinates we're really referring to the...

@David I'm afraid 42 furlongs per fortnight is a rate measurement not a distance measurement.

Welcome from Victoria. Wealth of information on this forum and really great members.

OK. While I wait for bearings to arrive to fit inside the TPU printed tension rollers I thought I'd take another stab at slowing down @David He's going way too fast on his CNC conversion but I think I've figured out a way to muck with his head. Recall he's had a CNC router for a number of years...

Nicely done! You deserve a pat on the back for that innovative solution.

There's an issue with the Arduino code I'm trying out. Once the motor is in motion it no longer can get the information from the encoder. But then the software on the Arduino was just to test out the motor driver.

A bit of progress. I'll post a link to a youtube video of the lead screw tracking the 400 line encoder.
