Re: Melzi motherboad - M42 Bed fan command hangs controller - 8 years ago
Update: I tried to use the arduino IDE over SSH with x forwarding to compile the firmware and download it (same result). The version is 1.0.5 from the debian apt-get repositories. (Linux octopi 4.1.19-v7+ #858 SMP Tue Mar 15 15:56:00 GMT 2016 armv7l GNU/Linux) deb jessie main contrib non-free rpi I suspect the arduino 1.0.5 produces a compiled firmware that doesn't respond well to the M42 coby cezar.suteu - Mendel90
Re: Melzi motherboad - M42 Bed fan command hangs controller - 8 years ago
Good news: I have tried to compile the firmware (exact same source code) on my laptop (Windows 10 PRO, arduino 1.0.1 with Melzi from copied into the hardware folder) and it works. Both the commands to start and stop the bed fan go through. The fan also works (my MOSFET choice was good). So it seems the ino compilation result on the Raspberry PI is not ok for some reason. All the other functionby cezar.suteu - Mendel90
Re: Melzi motherboad - M42 Bed fan command hangs controller - 8 years ago
I have done more tests (MOSFET is still removed) : Sending M42 P28 does not hang the controller (it replies OK to the serial command). In the Marlin code, the following lines exist: case 42: //M42 -Change pin status via gcode if (code_seen('S')) { int pin_status = code_value(); if (code_seen('P') && pin_status >= 0 && pin_status <= 255)by cezar.suteu - Mendel90

Hi, thanks for quick reply. I have unplugged the MOSFET from the Melzi header and the issue still persists after M42.by cezar.suteu - Mendel90
Melzi motherboad - M42 Bed fan command hangs controller - 8 years ago
Dear all, I have a Mendel 90 Dibond (2003 kit). The firmware I run is .I am flashing the printer from a Raspberry PI v2 based on instructions found in . Lastly I use Octoprint for managing my printer. I have tried to connect the bed fan for cooling by using the instructions provided in the Mendel90_Dibond.pdf (I used a IRLZ44N MOSFET for the Melzi spare IO). My problem is that when I run eiby cezar.suteu - Mendel90
Caut printer 3D - 11 years ago
Salut tuturor, Sunt din București. Încerc să fac un robot cnc/printer 3d cu lego și am nevoie de niște piese customizate. Am pregătit fișiere STL pentru niște modele de fulii și un convertor de ax. Ar putea să mă ajute cineva cu printuri, contra cost? Atașez fișierele. Mulțumesc, Cezarby cezar.suteu - Piața din centru
Longer LEGO steering gear - 11 years ago
Hi everyone, I'm new in 3D printing but really fascinated by this technology. I am building a prototype for a Delta style robot with LEGO NXT and EV3 sets. What I would like to use is a longer track rod for holding the gripper. The current design is using the following piece from LEGO: I've attached a picture also. Basically, I would like the same part double or triple in length. How couby cezar.suteu - Let's design something! (I've got an idea ...)
