Hello, I have this problem with a Wanhao Di3 converted to RAMPS 1.4, running with Repetier. I followed the instruction on the 3DPrinterWiki and after awhile I got it mostly working. I'm getting this problem where the X side of the 20x20x20 cal cube is to the left and the indent isn't deep, the Y side is too deeply indented and to the left, and the Z side is an incomplete Z shape and the top layby ScarletImpaler - RAMPS Electronics
I did manage to get the printer finally talking with Repetier. Oddly enough, I had to change baudrate settings in the Windows Device Manager (and changed the COM port to COM 3, was COM 5, for good measure, according to a random comment found on Repetier connectivity issues). And yes, I've tried all baudrates in Repetier before this. Which I haven't found a single instance of this fix in all my seby ScarletImpaler - Prusa i3 and variants
QuoteDust that firmware code is specifically for the orriginal prusa mk2, not for clones. It is hard-coded with values for that machine and presumes you have a inductive probe and a v42 bed with the 9 embedded probe points. (also presume things like probe is in same position as the mk2) From my experience with a mini rambo and that firmware until that firmware completes a calibration via the lby ScarletImpaler - Prusa i3 and variants
QuoteDust I would guess this pre made code is not normal or not for that controller.. how about some details, like from where did you downloaded it from? "Mini-Rambo build" doesn’t mean a thing other than to tell us its uses a Mini-Rambo controller. M907: Set digital trimpot motor The default are apparently #define DEFAULT_PWM_MOTOR_CURRENT {1300, 1300, 1250} so your values look really loby ScarletImpaler - Prusa i3 and variants
I'm at my wits end on this. I'm towards the end of this Mini-Rambo build, and everything works, sans the Y-axis motor not getting enough current and getting real jerky print bed movement, causing shifted layers. Belt is nice and tight, as tight as my Ultimaker belts. No matter what I do, I can't get the Mini-Rambo to talk with any of my PCs, except for that easy Marlin firmware uploader progrby ScarletImpaler - Prusa i3 and variants
Luckily, the brace that held the X-axis endstop was easily rotatable, so that is figured out, and working great. Tried to print and ran into another problem. The print wasn't staying in one spot, it started in one spot, and then each layer would be offset from the initial layer along the Y-axis (like the second layer would be about a 1inch off the initial layer, towards the back, and the thirdby ScarletImpaler - Prusa i3 and variants
Alright, I got these going, endstops and motors work. Thanks! But I just found another interesting problem. The X-axis moves in reverse, it moves both ways now, but homing the X-axis sends the extruder carriage in the opposite direction of the endstop.by ScarletImpaler - Prusa i3 and variants
Hello, I will be having a lot of left over parts from a heavy modified Wanhao Di3 project, I was thinking about printing and building a MendelMax 1.5 with them. I found a few listings on Thingiverse for them and got me interested since I should have most of the hardware already: Melzi board with LCD screen, end stop switches, heat bed with glass, frame, and optical rods, extra E3D hot ends.

Well, damn, I didn't even think that, I expected them to work properly without them. I'll check the end stops angle next! Thank you.by ScarletImpaler - Prusa i3 and variants
Hello, I'm currently upgrading my Wanhao Di3 from its Melzi board to the Mini-RAMBO and I got it mostly working. The problem is that the motors will only travel one way and not the other. I've tried all different combinations of wiring to the motors, but I kept getting the same thing. Anyone know what could be causing this issue? I am using the stock Wanhao motors, and the only other upgradby ScarletImpaler - Prusa i3 and variants
I suggest actually reading what I wrote and the article. I never said multiple feeders would be operating at the same time. I also suggest reading the article about it, as it was written by Joesef Prusa himself, before you continue talking about something you clearly don't know about. Here it is again: I suggest reading it before you talk more about it. Also, the help I need is in regards to wby ScarletImpaler - Prusa i3 and variants
Yes, Prusa's dual/quad extrusion solution using an external 2- or 4-way splitter to 2 or 4 Bowden feeders. The concept is that the extruder only has one nozzle, and only one of those motors will be operating at any time. When the extruder needs another filament, one Bowden feeder retracts that filament, and then another feeder pushes the next filament to the extruder. It goes back and forth likeby ScarletImpaler - Prusa i3 and variants
Indeed, I guess I was being too careful. This is the Mini RAMBo board: The kit comes with endstop switches, and wiring harnesses, but stuff like the LCD screen and power supply is what I'm worried about. Especially since there are some parts of the Maker Select/Duplicator that are off spec a bit, like the Y-Axis rods being closer together.by ScarletImpaler - Prusa i3 and variants
Hello, I hope its not taboo to talk about clones here, but I do intend on upgrading to legit Prusa parts, so I hope its kosher... I have two i3 clones that I want to upgrade the board to the Mini Rambo board, in anticipation for the Prusa dual/quad extruder coming out later this year, but I really don't know what else I need. At online stores, I'm seeing specific LCD screens and such, and I'lby ScarletImpaler - Prusa i3 and variants
