Trying to use(most use) custom Gcode X3G

Hello.
I have a Mbot cube upgraded to Grid 2+ and normaly use simplify3D or mbot own software.

The problem I have to slice with Astro cloud are the start sequense. the build plate I have uses “hols” for the extruder so it can auto calibrate.
so i move down and after it has home Z it try to go to “wait position” without give anny space for Z som almoste scrats the bed.

I have tride to use diffrent slicers, diffrent standard Gcode but No G code Works to get the Z axis down.

My 2 example that dossen’t work. And its look like it’s not trying to use the custom G code?

G21; set mm units
G28 ;home all axis
M190 S[first_layer_bed_temperature] ; set and wait for bed temp to be reached
M104 S[temperature] ; set extruder temp and start heating
G90; set absolute coordinates
G1 X 0 Y0 Z5 F300 ;move platform down 5mm
G1 X-100 Y-105 Z20 F2500 ; move to waiting position
M109 S[temperature]; wait for extruder temp to be reached
G1 Z[first_layer_height] F200 ;move platform close to nozzle
G92 E0; reset extrusion distance
G1 E7 ;extrude anchor

And another one

G21 ;metric values
G90 ;absolute positioning
M107 ;start with the fan off

G28 X0 Y0 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops
G92 X0 Y0 Z0 E0 ;reset software position to front/left/z=0.0

G1 Z15.0 F180 ;move the platform down 15mm

G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again

G1 X-90 Y-90 F9000 ;go to the middle of the platform

Is there a bug? Is it impossible to use Custom Gcode to X3D slicing?

Thanks.

I think the problem is that you’re using variables In he Gcode. For example “first_layer_bed_temperature”.

We don’t support this yet. We’re working on it abd it’ll be released very soon

Ok. So the reason it skip the hol custom start code is be curse on or more commands not supported?

Is there a list of what command as working right now. Or can you help me ?
I can use default start if son inr can add " move Z 5 mm down after home all axis"

Thanks for fast respond.
