Ok, the printer is working great. I can print directly from Repetier Host (USB), can also load the gcode to SD and trigger a print from SD using Repetier Host from the laptop over USB. HOWEVER, I cannot for the life of me figure out how to run a print from SD directly using the LCD. The LCD is from Joachim Zimmer's method (which works great) and I can browse the menu, settings, heat the extruder, move axis, etc. However, even if I heat the extruder, when I select a file from USB using the LCD, it returns to the "Watch" page and has the file name at the bottom but does nothing. I've waited, and nothing. If use USB from Repetier to run an SD print, start the print and then disconnect the laptop the print runs without problems and the "watch" page on the LCD shows the progress. I can also use the LCD to alter print settings real time (speed, temps, extrusion, etc). I just cannot figure out how to start a SD print without the laptop. Anyone know how, or if it's possible?
Also, a very strange behavior I don't understand but happens almost every time I have tried to start an SD print from LCD. While waiting for something to happen (and giving up), IF I plug my laptop back into the printer with Repetier running, the printer will start printing the selected SD file. I can immediately unplug the USB and it will continue to print normally. At first I thought it was just coincidental timing, but have tried it randomly and it almost always does this. Almost as if just initializing the USB connection releases the print.
- I am a newbie, this is my first 3D printer, and I am a novice at arduino. Learning and learning but google searches on this have come up nill.
I found an excellent post on Thingiverse that allows me to use Cura's software to slice my prints and export to gcode. I then use the exported gcode and import it into my Colido/PrintRite repetier software and my prints come out perfectly each time. The original post can be found here: https://www.thingiverse.com/groups/printrite-diy-3d-printer/topic:5624
The reason for my post is that Cura does not understand the position of my print bed and sometimes when I export the print and load it into my repetier software the printed item is outside the print bed area and I have to go back to Cura and move it around until it fits.
I believe this is configured using Cura's print head settings: http://i.imgur.com/PeecrZf.png
In order to match my printers settings (https://i.imgur.com/CvdoQ1l.png) I would need to enter minus values for the xmin and ymin however cura doesnt allow me to enter minus values (-15 and -20).
Does anyone know if this is possible? Or am I looking at the wrong settings?
Thanks in advanced for any assistance that you can offer!
Colido control board stopped communicating so I decided to upgrade.
Has anyone got a Config.h for ramps 1.4 or 1.6 for this 3D printer?
If not can anyone tall me which 3D printer in the list of Ramps Config examples is the closest to the Printrite?
I have all the hardware connected and only need to program the Mega in order to finish the upgrade.
I've been lurking for a while, slowly learning how to use my printer and I have a really dumb question to ask. I know the Colido Printrite DIY comes with a .4 mm nozzle; can you change the nozzle to say a .2 or .3 and change it in the software?
If that was possible, wouldn't that give you finer (if not slower) prints?
