Not changing z while printing acceleration tower

[UnconnectedBedna]

To start, this plugin is awesome!

EDIT!
I found out what it is, I analyzed the gcode and you start each layer with "G0 F9000 Xnull Ynull" the printer did not like that. I removed all instances of "Xnull and Ynull" and boom, it now works.

Super old cr-10.

Calibration-Companion 1.0.1
OctoPrint: 1.7.3

I'm using junction deviation (0.049, m503 reports 0.05 but that's ok, I think) and linear advance (0.45).

When making an acceleration tower at max height (9 stages) it produces the gcode, I can open it in cura and it looks correct (haven't analyzed the code but since cura shows me a correct model the gcode should be correct right?).

It starts printing, but the z axis never changes, it just keeps printing the same move over and over until the plastic gets stuck in the nozzle and comes of the bed.

I just wanted to test the accelerations so I set the same junction deviation on every stage (0.049).
I go from 200mm/s (stage 1) to 900mm/s (stage 9).

Tried making the tower smaller (less stages) but got the same result, no z changes.

The retraction tower works fine, haven't gotten to the flow test yet.

Adding a prime tower in the gcode would also be a good idea so I don't have to edit that into the gcode.
