Manual control X/Y erratic behaviour

Hi

I just found the following erratic behaviour on the manual X/Y control (on Raspberry PI gui w/ Renkforce RF1000)

I've homed all axes. For this example, I've set 10mm (happens on different values also)

- X position is 0
- I press "right"
- Extruder moves 10mm right
- I press "right"
- Extruder moves 20mm right
- I press "right"
- Extruder moves 30mm right (while X value on screen is now 30, Extrudes has moved 50mm)
- I press "left"
- Extruder moves 20mm right (shown X now 20, Extruder position now 70mm)
- I press "left"
- Extruder moves 10mm right (shown X now 10, Extruder position now 80mm)
- I press "left"
- Extruder doesn't move (shown X now 0, Extruder position still 80mm)
- I press "left"
- Extruder moves 10mm left (shown X remains 0, Extruder position now 70mm)
- I press "left"
- Extruder moves 10mm left (shown X remains 0, Extruder position now 60mm)

Continuing pressing X left acts normal, extruder moves always 10mm.
Pressing X right again and things start over.

Same behaviour on Y axis, while Z axis seem to operate normal

    Firmware should start up in absolute positioning mode. Looks like yours is operating in relative mode.

    Ah, that might be an explaination while I've never noticed this issue before (after I had a jub run), I've G90 in my start G-Code. Will doublecheck tomorrow and report back.

    Guess here is my confirmation pending. Agreed, G90 will solve this issue. I don't know why this RF1000 fork starts up in relative mode.
