Ft-5/Duet wifi/Cura Prints not homing properly, Help!
-
I just upgraded my board to the latest duet firmware 1.21, using Cura with the FT-5 printer. I can move around and home perfectly fine both with the individual axis and with the home all. The problem arrises when I try to print a file generated in Cura. After homing the printer and loading up a file, the head wants to move beyond the print area. The Z moves up into the head, the X moves further away in the + direction. My home position is in the upper right corner of the 300x300 bed, the Z is 400mm. My axis movements all begin in the minus X, Y, and Z direction from home as I am using the minus quadrant relative to my zero. I suspect the problem is in the Cura start code? Ive been trying to get up and running for four days now with no success. Any help on getting my prints set up in the middle would be great!

What firmware did you upgrade from? There was a bug fix regarding corexy motor direction. Might want to give the release notes a read for the versions between what you were using and what you upgraded to. I think your answer is in there.
You can verify your motor direction and axis configuration here: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Movement_section

The firmware version is the same, but I installed the duet2combinedfirmware, webcontrol1.22.3 and the duetwifiserver1.21.1. I'll take a look at the file, hope it helps. Thanks
-
The Cura start code looks fine, but it would help to see your homing files since that's what actually controls the homing moves.

My printer is not formatted for corexy but cartesian, via the manufacturer. Here are the homeall settings:

My mistake. I thought the FT 5 was corexy.
Try this instead.

I used this initially and definitely got the printer up and running, everything moves as it should. The problem is printing from cura, it wants to print in the wrong location. It seems to want to print in the positive XY quadrant when it should be in the negative quadrant. It looks like cura reverses the axis and start point. I posted the cura start code. Do you think its a problem with the G90 and G91 commands?
-
Can you post the first 50 lines or so of an actual sliced gcode file?
How do you have your bed setup in Cura printer properties?
Have you tried another slicer?
If you jog the printer manually does it move the way it should?

I just ran pronterface, tried to print and this is the gcode I got:
Center.gcode, 76886 lines
15026.67mm of filament used in this print
The print goes:- from 0.00 mm to 188.79 mm in X and is 188.79 mm wide
- from 0.00 mm to 188.79 mm in Y and is 188.79 mm deep
- from 0.00 mm to 25.10 mm in Z and is 25.10 mm high
Estimated duration: 126 layers, 1:16:11
Setting hotend temperature to 220.000000 degrees Celsius.
Setting bed temperature to 60.000000 degrees Celsius.

AttributeError: 'module' object has no attribute 'kCFStringEncodingASCII'Apparantly I have a few errors.
-
The machine missed a whole bunch of steps at the beginning of the print, it was trying to move beyond the print area to another quadrant. It should be printing in the center. Im not sure what to make of the error code.

Sorry, I meant "printrun" not pronterface.

this might help as I have a cartesian AM8

Are you printing from the DWC by uploading the gcode to the SD card or are you printing via usb?
How do you have the bed setup in Cura?

@starpowersolaryahoo-com not sure if this will help you but you may want to change to reprapfirmware gcode flavour

Aaa...nd reading that I just realized I forgot to comment out the first M305 when I put in a PT1000

@phaedrux It made no difference, same result. Im dead in the water here.

@stewwy We have different machines, but Ill try your settings. Thx

See my additional questions from a few posts up.

When sending a print, the XY motors start moving and skipping steps, then the they move to the wrong location and begin printing. Ive included a link to a youtube video that shows their behavior, https://youtu.be/uHj62Tgl_jw. Anyone have any idea of whats going on? Again the printer homes correctly but reacts like this when attempting to print.
