SoliForum - 3D Printing Community → Help/Repair/Maintenance → Carriage going to lower left corner after print??
My small frame SD2 (after sending back a broken machine and getting a different machine to save time) always finishes a print job, lowers print bed, X and Y homes, and then when the print bed stops lowering the carriage retreats to the opposite corner and jams in there. Anyone else have this issue? It doesn't do this when I kill the job, and support has remote access changed my settings on Repetier twice already to no avail.
Yes, my new SD4 does the same thing. Home is back right. When a print finishes or I kill a print it goes to the front left and jams into the corner. I have had other higher priority problems I have been solving.

Simply copy and paste to your gcode in slicer. You can also tweak the code to your liking.

That doesn't sound like the same thing. And when my settings were updated to what he said were the current defaults he cleared all start and end gcode. Incidentally before he cleared those settings the gcode for end and kill job were identical. And as I mentioned it doesn't occur when I kill the job.
I had the same problem with my SD 4 when I tried to run start/end g-code...
I don't remember exactly where it is - in the printer settings in RH i think (not at the printer computer right now) - but there are boxes for the "park" position - they were all set to "0" across the board by default, I had to enter the correct numbers for X & Y to get it to home and stay there.
position "0" on an SD is front left - Home is going to be whatever your printer designates for a given axis... on my SD 4 it was 205 & 200 for X & Y
Ok, verified the location of the setting that needs to be changed to stop the printhead from slamming into the left front corner at the end of a print job and/or killing a print...
In RH, under "config"
click on "printer settings"
select the "printer" tab (second from left)
enter the X and Y axis home positions in the "Park Position" boxes for each (manually home each axis and enter the number shown in the manual controls) "Park Position" is found about 2/3rds of the way down the window, under the adjustment for checking temps. Also, make sure the check box for "Go to park position after job/kill" is checked.
I did leave the Z axis at 0, and it simply stays where ever it is at after completing a print
Yeah I reinstalled Repetier and noticed the park position check box. It still hits the corner so I hope that is the issue right there. Thanks for the feedback. I hate having to cut the power on the printer right after it finishes to avoid the impact. lol.
My park position was set at 159, 150, 50 which I think is correct for my SD2. I was thinking it was the opposite where homing was the 0,0 origin. I reset them tonight at 100, 100, 50 thinking it would end up in the center somewhere. It still hit the corner and it seems like it kept hitting the corner longer than normal. Maybe higher numbers will push it more to the opposite corner? Maybe something is inverted somehow?
I have an sd 4 so a little larger bed therefore higher numbers.
My park is set for x 180 y 180 z 50
this gets the head out of the way without hitting the home switches.
Home should be x max y max z min
x min 0 x max 200 bed left 0 (your max numbers should be about 150)
y min 0 y max 200 bed front 0
With this configuration all work is done in the ++ sector of the Cartesian plane.
Home is x max,y max, z 0, the front left corner with the bed up is 0,0,0
hope this helps

I don't see anything that isn't set correctly. Is the following end and kill codes normal?
END
G28 X159 X 150
G91
G1 Z50 F50
G90
KILL (Same)
At this point it seems I should just unclick the park position box? It already homes at end of print.
Start code includes
G28 X0 Y0
That seems to be what homes it.
when you manually home the axis, what numbers show in the boxes on the manual tab?
it is those numbers for X & Y, or close to those numbers, that you need to enter into the "park position" boxes in the printer configuration.
Your END Gcode should also say G28 X0 Y0.
It should not say G28 X159 X 150 which I assume is actually G28 X159 Y150. With those values in your end code it will send the head to the opposite corner of the home/start position.
Solidoodle uses max values for home, not mins... My SD4 says X - 205, Y - 200 for home positions
so for his smaller SD the numbers are correct

But his numbers are positive numbers, not negative numbers like yours.

159 and 150 are where carriage says it is after homing.
I will consider setting park numbers to 0 but not before simply uncheck box.
mine are not actually negative numbers... the "-" was just a spacer - guess I shouldn't have used it in this context.
Rocketman - unchecking the box is not going to help when you have ending g-code entered - I tried that & it didn't work - you really need to enter the home values in the park position boxes. The only things that stopped the crashing for me was to either remove the ending g-code (which left the printhead over the print where it could melt stuff and/or ooze on it) or putting the correct numbers in the park position boxes.
I suppose you could also modify the ending g-code to reflect the correct home positions as well.... but 0 is not it.
This is the problem. The home coordinates and park coordinates are the same. It finishes, it homes, and then it crashes the opposite corner. I am thinking the two must use different coordinate systems or something valuable has been left out of my SD2 small frame firmware.

The system will only move if a gcode command makes it do so. That being said there is code at the end of your gcode making it do that final move. you need to see where it is and then figure out the source. Can you post the start of one of the gcode files as well as the end. You can just leave all the middle stuff out. I am just interested in about 20 lines of the start and end.
How do I find these files? They aren't simply the code displayed in Repetier?

Just export the file rather than print it. Then you can open it in notepad.

Can you instruct me on how to save this file?

When you slice a file in Repetier Host it save the file as Composition.gcode in it's working directory. To find the working directory just click on file up on the tool bar and select show work directory. As said the compostion.gcode file will be the last and should be current file that you have sliced. That is your gcode file and can be opened in notepad.
