Repetier Server Disregards Start and Ending Homing

timere969

Hello,

It seems that Repetier Server disregards homing G28 (G28 X0 Y0) at the beginning and end of prints.  I have it in both the slicer gcode and the printer settings start and end setting.  If I manually send the command outside of a print it works.  I have autolevel G32 set up and it works great, but it will start from the current position without homing X and Y sometimes missing the bed.  At the end of the print, it will leave the nozzle on the object without homing x and y fusing to the object and melting a hole.  I've tried moving the command to before and after M104 S0 and it doesn't seem to have any effect. 

Repetier

I tested the servers start/end script an dit seems to be send, only on pause start I'm not sure at the moment.

Can you post a small gcode (small cube) you printed and a log of the print. The log should exactly show what got send and if there is a problem somewhere.

How do I attach something.  It says it is too many characters.  I'll try and post the start and end code.

I modified the start and end gcode on the server to be
G28 X0
G28 Y0

Seems to be working better.

timere969

It homes, but does not shut off the heater. Looks like it follows the commands from the server settings, but not from the slicer.

Repetier

It seems to shut down heater

< 14:11:22.801: N5983 M104 S0 ; turn off temperature

get executed and temp. set is 0 afterwards. What I see is that the G28 after 

G90 ; absolute positioning

gets skipped. There is no visible reason for that, so it might be a strange return so G28 is takes as comment to the line before or some other non visible character letting the server assume it does not need to get send. This would require the binary file for inspection. Could you put it in your dropbox or pastebin for download so I can see what is not visible.

timere969

Do you want the GCODE, STL, or LOG?

Repetier

The gcode is what I need. That is where the server skips that line as it seems from your log. So there must be the problem.

timere969

I put it in Dropbox.  Who should I address it to.

Repetier

If it is non critical just post the link here or send me a pm with the download link.

timere969

https://www.dropbox.com/s/bpl5lnnsbbb7l3s/PETG-1.75mm-234C-Y_Motor.gcode?dl=0

Repetier

Ok, that was a harder one. The reason is that the server thinks the command is invalid so G28 gets ignored. I have fixed this for the next release. Until then just make sure that you have a space between command and comment sign. So

Bad: G28; Home

Good: G28 ; Home

timere969

I've been putting the commands on the server side instead of in the slicer,  seems to work pretty well now.
My Start Code on the server side is
G28 X0
G28 Y0

My End Code is
G28 X0
G28 Y0
M140 S0

Had to add the M140 because the heated bed was not turning off.

Thank you for your help.

Repetier

They work beacsue you have no comments. Adding the space before the semicolon comment in slic3r start/end gcode would also have worked.
