yes. I played around with Cura last night a little.
This may also help a bit.
Printing pretty well at the moment.
Any risk in installing a larger internal fan while I'm in there hooking up the LCD?
Mine are both 3.5" fans.
Use whatever you want. You do not even have to power them off of the RAMPS, just power them directly from the 12v supply.
@Curtis Wolfe I have an 80 x 80 x 15 mm fan installed in the bottom of my Robo. It is much quieter than the 40 mm sq fan originally there. It blows a lot more air. Even on the hotest days I have no fear of overheating the Arduino/RAMPS boards even with prolonged printing sessions.
Thanks guys. I picked up a 80mm fan yesterday. I figured I may as well while I have opened up.
As soon as the bottom of the LCD case is finished printing. I came across a 2lb (.9kg) roll of translucent orange at Fry's for $11 the other day. So, the next thousand prints or so will be orange. LOL
@Curtis Wolfe I hope that fan isn't too thick, you only have about 16-18 mm of clearance from the bottom cover to the RAMPS board, anything larger than that won't fit.
Hmmmm. I guess we'll see when I open it up tomorrow.
So, I have the LCD installed, and Cura installed on the PC.
Three things when I send the print to the printer from the LCD screen.
It doesn't go through the auto leveling
It doesn't know where the printed bed center is. It's trying to print off the bed
The Z offset is way too far from the bed
I guess I'm making progress. Haven't been able to print for the past 24 hours
Should be something like this (at a bare minimum):
You have to have defined the printer (X/Y/Z sizes in Cura somewhere too)
Curtis, what is your process?
You are just saying
Lot's of assumptions can be made like you did all the steps or you are not doing the correct steps.
1. load your .stl file into your slicer software.
2. Save the gcode file to a memory card.
3. Transfer the card from the pc to LCD controller.
4. Choose the gcode file on the memory card to print and print.
I know this sounds funny, but when I started I actually was copying the .stl file to the card and trying to print from the SD slot on the printer.
What ever settings are set in your slicer software (like MatterControl or Cura) these are transferred to the SD card in the gcode file. Auto level should be a part of the process too.
1. load your .stl file into your slicer software. YES
2. Save the gcode file to a memory card. YES
3. Transfer the card from the pc to LCD controller. YES
4. Choose the gcode file on the memory card to print and print. YES
The Start up Gcode is
G92 E0 ;
M565 Z-1 ;
G1 Z5 F5000 ;
G28 is the auto level isn't it. I don't see it here.
I really appreciate you guys helping me out.
G28 homes it initially it won't do most of the other if not homed first.
G28 ; home all axes
G29; init autoleveling
G29; will not happen if it doesn't home first.
I copied your Gcode start up and stuck it in there Mark. Let's see what happens
Nothing it just heated up to temp and didn't do anything
Well, It homed itself and then did the auto leveling, but it's still trying to print off the bed.
Adjust that M565 value.
Like I said more negative is further off the bed (not what you want) more positive is closer to the bed.
Do it in small increments (0.01)
It is not usual for -1.0 to be the correct number
It is a starting point
Paste in the first 50 lines of your GCode too. We can see if it is doing anything odd.
I'm sorry. Not the Z off set. It's not initiating the print in the center of the bed. It's trying to print in the front left corner where its hitting the stopper switch.
