G54-59 not working in start.g?

TC

Hi all,

is it possible the alternative coordinate systems are not working in start.g.
The following code:

G55
G1 X0 Y0 F2000

just executed in console moves the head to the origin of system 2. But executed in start.g or a from there called macro it moves to the origin of the absolute system...

Thanks ahead

For debugging, add G10 L2 with no other arguments. This will print offsets for the current work system on the console.

This can also be the second command on a line, so this is a good way to do this for debugging:

G55 G10 L2

G55 G10 L2

I tested it. It displays the correct offsets of system 2 even if it is executed from start.g. still the next G1 command goes to the wrong place...

Wow, that's really not good.

What releases are you running? Check the "machine specific" tab in the web interface, and copy the three lines that look like this (you may or may not have a DSF line):

Board: Duet 3 MB6HC (MB6HC)
DSF Version: 1.2.4.0
Firmware: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 3.01-RC2 (2020-02-18b1)

Board: Duet WiFi 1.02 or later + DueX5
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.01-RC1 (2020-02-08b3)
Duet WiFi Server Version: 1.23

But the problem allready existed before the upgrade to RRF3

Hmmm... you could try RC2, just for completeness. It uploads just fine via web "system" tab.

Ahhh... interesting. I'm really stumped as to what would cause this, it would seem this is a function of a very basic parser that should work for you and me both.

Hmmm... @dc42 will probably need to look at this one.

Commands in macro files in the /sys folder always ignore workplace offsets. This is so that movement commands in homing files, pause.g and so on always go to the same places regardless of what coordinate system you are in.

TC

Ah ok. In my case I set the origin and therefor the place to print before each print job. That is important because I need to print on prepared objects. Is it possible to add the function that if there is a G55 command directly in front of a G1 command it applies the offset?

TC

Or is it possible to get the offsets of the coordinate systems from the object model?

TC

Ah looks like I found it

TC

Thanks to your awsome object model it was easy to solve!

Very interesting and good to know. THANKS!
