Hi Folks, I don't want to use the "big" mosfet to control my bed heater since I am using an external mosfet which only needs a signal to turn it on or off. What GPIO can I use? I want to use the 2.5 pin to control a strip of LEDs. Thanksby rrowan327 - Smoothie
Hi Folks, I know this is 2 months old but I was looking for the same answer. After searching Marlin's Github site I found the answer. Marlin fw ver 1.1.0-RC8 Edit ultralcd_impl_DOGM.h un-comment line 380 define DOGM_SD_PERCENT save and upload to your arduino. Hope that helps someone Rickby rrowan327 - Firmware - Marlin
My best guess would be a clogged hotend. Try something like this Clean Hotend Hope that helps.by rrowan327 - General
Just attach something thin to your printer that will slide inside the endstop. Use anything you like, metal, plastic, etc.by rrowan327 - Prusa i3 and variants
I created a new part. Its for a Slik tripod quick release base. I plan to use it to attach other devices to my tripod like a smart phone or tablet once I design holders from them. This is still a learning process but I need the diversion from work and real life. Enif, the code for the y axis is base from your code example. Rickby rrowan327 - OpenSCAD

Hey enif, Just showing (off) with what I was trying to do in openscad. Now one part I did cheat and "borrow" some code from thingiverse. That person create an RC car wheels with the center spokes being a hazard symbol. I thought it was an interesting design and used the spokes part.I am not happy with the code yet (doubt it will ever be perfect ) Thanks for your help, I am still trying and hoby rrowan327 - OpenSCAD
Is this the kit you are looking at? Github Kit from Prusa If so there are two file types in there 1 - STL is the printable version of the files, Openscad is not needed for these. 2 - SCAD files can be open in Openscad and modified if needed. You can just down load the whole folder to your computer. If you need them on a cd then you should be able to select that folder and drag and drop them (inby rrowan327 - Object repositories
Hi me again, Just going over the code to make sure I understand it. module slotcutout(opening=10) { ** This rotate is no longer needed since the hull command makes the shape properly ** rotate([15,0,0]){ ** hull forms the required shape using the top (cube) then two cylinders for the bottom corners. ** hull() { **top section with cube command and the use of opening constant is cooby rrowan327 - OpenSCAD
Hi enif, Many thanks for the help, the code works perfectly. I didn't mean to say I wanted to use the drawing from auto cad but it was just to show what i wanted to do. My goal is do all part design in opens cad. Thanks again Rickby rrowan327 - OpenSCAD
Hi folks, I am working on a simple part to learn more about Openscad. I have the basic shape done but I wanted to change the slot cut that holds a tablet. Since I don't fully understand how to use polyhedron which I think is what I need or maybe some other command, I created a basic shape in Autocad to show the new slot cut I want to use. I can export the part as either stl or dxf and import intby rrowan327 - OpenSCAD

Sorry about replying to an old topic. I am still learning Openscad but I have been a hobby programmer for many years. I slightly modify o_lampe's code to use a for loop difference () { union () { translate([0,0,3]) cylinder(10,3,3,$fn=100); //main cylinder intersection(){ translate ([0,0,6]) sphere(6, $fn=100);by rrowan327 - OpenSCAD

If you download the firmware zip file from therippa and unzipped the file then you already have a "working" version of the configuration.h. I don't know if you properly upload the new firmware to your Arduino board using the USB cable between your computer and the Arduino board (Marlin version should now be 1.0.2). M119 is a g-code command to the 3d printer (g-code is what 3d printers and cnc macby rrowan327 - Prusa i3 and variants

Quoteejnelson first question for you all, I've been printing ABS at about 185 and PLA at 170 and just started PET at 175. I've done push plastic, microcenter inland, sainsmart, and hatchbox so far and they all fall into about those temperatures. I have done PID tune on my hotend. I've gotten some great prints, only major problem has been the stringies from the nozzle which seems to be a common prby rrowan327 - Prusa i3 and variants
