Re: Red LCD switch - 10 years ago
I don't see any red buttons at all, but they one on the RAMPS board and the one on the display are both reset buttons that mirror the function of the reset button on the Arduino. They reboot the Arduino.by MindRealm - RAMPS Electronics
Re: need help with prusa i3 - 10 years ago
Please let me know what firmware you're using (Marlin, etc.) and info about your end stops: X-axis on left or right, Y-axis on front or back, and Z-axis on top or bottom.by MindRealm - General Mendel Topics

Probably going to go with 3/8" due to easy sourcing here (US) compared to 10mm. Although I may actually print all 10mm, and use printed 10mm bearings with 5/16" rods. Decisions, decisions...by MindRealm - Look what I made!
Re: prusa i3 first print problems - 10 years ago
OK, so the result 19:17:16.237 : X:200.00 Y:200.00 Z:0.00 E:0.00 Count X: 200.00 Y:200.00 Z:0.00 means that the printer is not at 0,0,0, where the slicing software begins. Try running G1 X0 Y0 Z0 before starting your print. (don't home the axes again, just run the command...)by MindRealm - Printing
Re: Which board did I fry? - 10 years ago
Quotetjbonzo I get power and L LEDs lit when I connect the arduino (by itself) to my USB, but any download eventually times out. I assume and hope it was only the arduino that got fried (and not the RAMPS, etc.). I would start by removing the RAMPS board from the Arduino and working toward getting it to connect to your computer. If you cannot connect (not found on the USB, timeouts, etc.) then tby MindRealm - Reprappers
Re: prusa i3 first print problems - 10 years ago
Home all axes then run M114. (It should return X=0, Y=0, Z=0) Then enter G1 X100 Y100 and see if the nozzle moves to the center of the bed. Run M114 again and see if the printer knows where the nozzle is located... my guess is that it doesn't, and is trying to print off the boundary of the bed.by MindRealm - Printing
Re: Problems with my Folger Tech Prusa I3 - 10 years ago
They should have been in the anti-static bag with the RAMPS board. Email Dan (dan@folgertech.com) and let him know you didn't get any... maybe he can help??by MindRealm - Printing
Re: Motors spin the opposite direction - 10 years ago
I believe he's referring to the pot on the stepper driver. However - The pots on a A4988 is on the opposite end than on a DRV8825... The firmware defaults are generic placeholders. They should be changed to accommodate your printer wiring.by MindRealm - Reprappers

Re: Problems with my Folger Tech Prusa I3 - 10 years ago
You should have received 15 jumpers with your FolgerTech kit. This gives you three spares (not being used at the E1 stepper socket) that you can use. Also, they are the same as used in computer equipment, hard drives, etc. What do you need them for?by MindRealm - Printing
Re: Problems with my Folger Tech Prusa I3 - 10 years ago
QuoteGoosey73 Does it matter if the y motor is in the front of the machine? No. The location of the Y-axis motor doesn't matter as long as the bed moves forward when sent forward, and to the rear when sent toward the rear. This can be changed easily by reversing the stepper motor plug at the RAMPS board or in the firmware. QuoteGoosey73 Also it looks like you have jumpers on some of the unusedby MindRealm - Printing
Re: Perimeter width and extruder steps - 10 years ago
I get really nice top layers with my slicing software (Slic3R) set to extrude top solid infill at 75% width. It fills all the gaps and provides a finer pattern.by MindRealm - General Mendel Topics
Re: Help help debugging pictured problem. - 10 years ago
May be a slicing problem too. It looks line the circle in one of your images is resulting in a hexagon... I see that the path preview shows circles in every case, but the printer is not simplifying the path - it only follows the G-Code. Please attache one of your G-code files (preferably the one with the hexagon result) and let someone else give it a whirl... may be insightfulby MindRealm - Printing

Re: folger prusa i3 not working right - 10 years ago
Oh. You'll need to add the library in your Arduino IDE. Download the library here: U8glib zip file and save it to your desktop (or wherever you can easily find it). Then, launch the Arduino IDE and click Sketch > Import Library... > Add Library... and select the zip file. This installs the bitmap and text support for LCD displays, and should remedy the compile error.by MindRealm - Reprappers
Re: Help help debugging pictured problem. - 10 years ago
I would start by decreasing the extrusion width and layer heights to 0.2-0.25 since you're using a 0.3mm nozzle.by MindRealm - Printing
Re: folger prusa i3 not working right - 10 years ago
Sure, but keep in mind that it is set up for my printer, as below: 190 x 190 bed (since I am now using corner clips for my heated bed glass) Servo mounted Z probe All axes are using min end stopsby MindRealm - Reprappers
Re: Auto bed leveling Z Lift before retract probe - 10 years ago
Maybe moving the do_blocking_move_to(current_position, current_position, current_position+3); to the beginning of the engage code, and compensating for the 3mm by reducing the 'lift before probing' value in Configuration.h? Hmmm...by MindRealm - Printing
Re: Auto bed leveling Z Lift before retract probe - 10 years ago
That's normal. I have been tinkering with the code to adjust the sequence from deploy-doubletap-retract to deploy-doubletap-raise-retract, but haven't had much time to work on it. For anyone else that wants to take a look, the code is in Marlin_main.cpp in Marlin: static void engage_z_probe() { // Engage Z Servo endstop if enabled #ifdef SERVO_ENDSTOPS if (servo_endstops > -1) {by MindRealm - Printing

Re: Folger Prusa i3 Kit from ebay - 10 years ago
Two comments on hot end jams: 1 - Proper cooling is essential - The ONLY place that filament is supposed to be hot enough to melt is in the heat block and nozzle. Any melting above that will cause jams. Having the heat sink in good contact with the cold end block and the fan on 100% all the time, and insulating the hot end to prevent radiated heat are the first steps in solving this problem. 2by MindRealm - Prusa i3 and variants

Re: Folger Tech Prusa i3 printing problem - 10 years ago
When you home to the right rear, having the X and Y end stops set as negative end stops, the printer thinks that it is at the left front of the bed, and will not move further. You'll need to disconnect the end stops from the X-min and Y-min positions on the RAMPS board and move them each up one space to X-max and Y-max. (Z-min is okay where it is) This will make your mechanical settings agree wby MindRealm - Printing

Please post your Configuration.h and I'll take a look.by MindRealm - Printing
Re: Auto bed leveling for Folger tech Prusa i3? - 10 years ago
Please let me know where your end stops are mounted, and where they're plugged into the RAMPS board. (a photo of the RAMPS wiring would be helpful) so I adjust your Configuration.h file accordinglyby MindRealm - Prusa i3 and variants

My bed leveling works great. I'm happy to help... Please post your Configuration.h from marlin and I'll take a look. Also, are you using Pronterface? I added a pre-print section of G-Code that takes good care of it automatically!by MindRealm - Prusa i3 and variants
Re: Folger Tech Prusia i3 Build - Z Axis End Stop Not Functioning - 10 years ago
You can switch the direction of the X-axis (or any of them) in this section, but changing true/false: #define INVERT_X_DIR true // for Mendel set to false, for Orca set to true #define INVERT_Y_DIR false // for Mendel set to true, for Orca set to false #define INVERT_Z_DIR true // for Mendel set to false, for Orca set to true #define INVERT_E0_DIR false // for direct drive extruderby MindRealm - General Mendel Topics
Re: Folger Tech Prusia i3 Build - Z Axis End Stop Not Functioning - 10 years ago
Your X and Y end stops are installed in the MAX locations, but plugged into the RAMPS board as MIN end stops. You'll need to move the plugs up one space, but leave the Z end top plugged in where it is. Also, change the following in your Configuration.h file: #ifndef ENDSTOPPULLUPS // fine Enstop settings: Individual Pullups. will be ignord if ENDSTOPPULLUPS is defined #define ENDSTOPPULLUPby MindRealm - General Mendel Topics
