Unexpected X movement on tool pickup.

duetlover

Hi everybody

I'm using E3D Tool Changer.

When a tool is not used, the temperature respects Standby configuration.

For exemple active 220°C, 200°C Standby.

I want that when a tool is selected, the heat up comes while tool is still parked, not after it has been took and moved to bed.

So I tried playing with tpre.g file

I tried with M116 without success.

;Unlock Coupler
M98 P/macros/Coupler - Unlock

;Move to location
G1 X212.9 Y200 F50000

;Move in
G1 X212.9 Y230 F50000

;Collect
G1 X212.9 Y242.5 F2500

;Close Coupler
M98 P/macros/Coupler - Lock

M116 P2; heat up

;WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING! WARNING!
;if you are using non-standard length hotends ensure the bed is lowered enough BEFORE undocking the tool!
G91
G1 Z10 F1000
G90

;Move Out
G1 X212.9 Y150 F4000

It always moves to the bed and then heat up...

Thanks !

Your M116 should be in TPost

https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Tool_change_files

You probably need to move your "move out" code there as well.

@OwenD

Moved to tpost and it works, thanks !

@sylvain

So I moved :

;Move Out
G1 X212.9 Y150 F4000

from tpre to tpost, after M116

So it works as it heats up before move out.

But when it moves out there a little x movement where it should not be...

I think it is a relative/absolute issue but I don't find the way to solve it...

Thanks !

What firmware version are you using? M115 to find out.

Here it is:
RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)

I've edited your post title to match your current issue with X movement on tool pickup.

@Phaedrux
That's exactly the issue

I partially solved the issue by replacing :

G1 X212.9 Y150 F4000

to

G1 Y150 F4000

but even if there was X212.9 it should not move on X at all.

@sylvain do you have a G10 offset which is moved when you change the tool?

@JoergS5

In fact I have in config.g:

G10 P2 X-9.0 Y39.5 Z-4.8

And I believe that the x movement is 9mm (when I look on web dashboard, I calculate a 9mm x movement)
