Single axis "printer" possible?

whopping pochard

Hi all,

I've been working on putting together a little rig for empirically testing hotend components (because I'm a giant nerd, I love data, and had an extra SKR 1.4 board laying around).

I have it set up with a basic extruder and groove mount block for pushing plastic, as well as with a second groove mount placed below a tiny linear axis. The idea is to write a gcode macro to take temperature measurements at 0.1 mm increments across the heat break.

Is it possible to just define a single axis, and still have it home that axis and accept subsequent move commands? Should I assign it to a non-XYZ axis name? Any other hints or suggestions?

Thanks!

@whopping-pochard in your homeall file, just remove everything and write g92 x0 y0 z0.
You will be able to "print".

Most certainly.

What Duet hardware are you using and what firmware is it running?

It doesn't matter what you name the axis unless you need to use the Z probe features in which case name it Z.

You will have to write your own gcode files for testing of course.

@jrockland Ahhhh that is what was tripping me up! Thanks!!

@fcwilt Thanks! I’m running the latest 3.x firmware on the SKR 1.4. My original Duet boards are all in actual printers.

I doubt you will be able to get it to work unless you use a Duet board.

@fcwilt why not? its exactly the same firmware (although the LPC version does have a few limitations, only due to memory constraints though)

Did you not see the "wink"?

I was just messing with him for not using a Duet product.

Poe's Law strikes again!!

But I did include the wink as required.
