Thanks Anvoice. I managed to get a 6mm Acrylic/Plexiglass and Polycarbonate sample sheet to see how easy they are to work with. I'm also considering these as alternatives to MDF should the Aluminium route be too expensive. I am also considering redesigning my Prusa frame to use an enclosed structure like that of the Ultimaker Original, rather than the open Prusa frame. I would prefer to keep thby josef.van.niekerk - Reprappers
Thanks for the replies so far. I didn't think that ambient temperature plays such an important role, and is possibly one of the reasons I'm not getting consistency. It was around 18°C in the house when I tried to setup and calibrate. I think I'm going to try a different print surface next time and moving from a bowden setup to direct drive.by josef.van.niekerk - Reprappers
I've been working quite a few months at building a RepRap Prusa i3 and designed a frame I can build with 6mm thick MDF. I don't take credit for the design, this is simply taken and inspired from many designs already out there. I drew up a design in Autodesk Fusion 360, as I simply wanted something up that I could print, stick to MDF and run through a scroll saw, or perhaps even laser cut. I couldby josef.van.niekerk - Reprappers
Found the problem with the LCD. Firstly I had to swap EXP1 and EXP2. Secondly, the potentiometer is a bit funny, the range at which the LCD display is visible is very narrow, so managed to get the contrast just right.by josef.van.niekerk - General
I have a RUMBA board, and I'm trying to connect a Full Graphic Smart LCD Controller from ReprapDiscount to my board. The LCD never turns on. Currently I've connected EXP1 from the LCD to EXP1 on the board, and the same with EXP2, with the red wire on the ribbon cable, closest to the black triangle on the RUMBA PCB. I've loaded the firmware, hotend and heatbed are heating up, motors are working fiby josef.van.niekerk - General
Thanks for that 3dkarma. I guess also that the worst that could happen is to reverse the x-axis direction, meaning models will face to the back of the printer, rather than the front.by josef.van.niekerk - Mechanics
Hi everyone. I have a quick question on a Prusa i3 frame I'm modifying/designing and just wanted to know if it matters whether the X endstop is located on the left or the right of the printer frame? I'm planning on using Marlin with a RUMBA board, and the design would be a tiny bit simpler, and wires shorter, if I could incorporate the x endstop on the same side the x-axis stepper motor is locateby josef.van.niekerk - Mechanics
