Hot end assembly moving out of print area

Hot end assembly moving out of print area
November 20, 2016 06:56PM
Hello
I am new to 3D printing, I purchased the Anycubic Upgraded Pulley Version Unassemble Delta Rostock 3D Printer Kossel Kit Large Print Size from Amazon. I had no issues assembling the kit. I've had issues with the firmware, hence coming here. I have set up the Arduino, Pronterface, and Slic3r with assistance from a friend who has a delta printer but not the same machine. We have gone through the code and are unable to discover the cause. I have a TriGorilla Integrated Main board Compatible Mega2560&RAMPS1.4+5xA4988. I have attached screenshots of Pronterface, and Slic3r settings that seem applicable. Also here is a link to a video of the event. [www.youtube.com]

I had to cut out much of the code for Configuration.h and Configuration_adv.h to make it fit this post. I've never used the formatted code button and wanted to get what seemed to be the important parts up for now. If more of the code is needed please inform me on how the formatted code works and I'll post it. Thanks for any assistance in advance.

Re: Hot end assembly moving out of print area
November 21, 2016 11:01PM
Through the youtube video I posted, I recieved a comment about the Pronterface/Slic3r not being set up correctly. After looking at this if i zoom out in Pronterface I can see the print item off to the side, where the printer is trying to go. I can't figure out where I need to go to put the item in the middle of the print bed!
Re: Hot end assembly moving out of print area

Hi mate,

Give this g-code a go, its for a 25mm cube

Its sliced with slic3r 1.2.9,
setup for my kossel mini
180mm bed diameter
for PLA temp is set at 190 (You can change this if you open it with notepad)

If your printer prints fine then you know its your slic3r settings, I would recommend updating to the new 1.2.9
If you still have the same issue then it could be the host software ( Try repetier host), or could be something in the firmwear try marlin (https://github.com/MarlinFirmware/Marlin)

I had to move my X axis limit switch 1 inch over to the left . Otherwise all of my prints were too far over to the left. Now they are center. My printer is a Prusa i3 Reprap.

well is your slicer bed parameters setup correctly if not then you will witness your issue, it looks to me that your slicer set up for a cartesian machine then a delta coordinate setup


Check my rubbish blog for my prusa i3

OK sorry everyone who responded, I've been really busy. I did find the cause of the issue, it's lame it was the X and Y offset in Pronterface. They were set at 100, this makes sense to me now, like I said I'm new to this. I do have the issue on Pronterface with the item not being displayed on the center of the bed. It will print in the center though. It's likely something simple but I haven't found it yet.
Sorry, only registered users may post in this forum.
