Heightmap with modal gcodes #261

Closed tetref closed 1 year ago

tetref commented 1 year ago

I don't know if I'm writing this correctly: I have a post processor that creates a circle with modal values X Y I J such that it logically omits some, eg G3X0I10J0. If I apply Height map to such code, error 33 occurs on the first line with G3. It seems to replace or add the missing value X to Z. So the line looks something like this: G3X17Z0.196I-10J0 I tried different gcodes. I have no problem with this code before applying. Only after setting Y as nonmodal is everything fine. The problem is with all versions of the program. For circle G3, must all values be non modal except Z?

Do you have an example (including a height map file)?

I belive I have fixed this, but I want to verify with a more comprehensive piece of gcode before release. This has to wait until I am back home later in January. Until then you may use File > Transform > Arcs to lines before applying the map as a workaround.

Can you try the latest edge version?, available from here.

tetref commented 1 year ago

Neither version 2.0.42p0 can be started, it reports an error. Copying the App.config from another version didn't help either. IoSender_error

terjeio commented 1 year ago

I've tested the standard version after downloading the zip and it works for me. Can you translate the error message? Which controller are you using?

tetref commented 1 year ago

Info from 2.0.41

[VER:1.1f.20221101:] [OPT:VNMZSL,35,1024,3,0] [AXS:3:XYZ] [NEWOPT:ENUMS,RT+,HOME,ES,TC,SED] [FIRMWARE:grblHAL] [NVS STORAGE:*FLASH] [DRIVER:STM32F411] [DRIVER VERSION:221014] [BOARD:BlackPill]

The index is outside the field bounds. Probably the correct translation is : "Index Out of Range Exception".

Thanks, that helps. Fixed versions uploaded now.

tetref commented 1 year ago

Version 2.042p1 seems to work ! After loading the gcode, the circle appears as a hex, and after applying the heightmap, it appears as a "perfect" circle. Perfect, seems to be fixed, thanks...
