Hum, I don't think the SLUM project was completed, Maybe I can use my old Sanguinololu PCB to act as a stepper expansion board like here: http://richrap.com/?p=121 Did someone tried to use 2 nozzles in one hotend to manage just on temperature hotend with two material ?by fujisama - Huxley
Do you think that's possible with: - Huxley dual nozzle holder or RepRapPro Dual Hotend - Sanguinololu Upgrade Module, is it compatible with marlin ? - Slic3r to generate the g-code my confg is: RepRapPro Huxley Snguinololu 1.3a Marin 1.01by fujisama - Huxley
For those who want to use RAMPS with the RepRapPro Huxley, here is an answer from reprappro support to configure marlin: "You may need to change the steps per mm, or printed parts will come out the wrong size. I think you have an older Huxley kit with T2.5 belt, and probably 14-tooth printed pulleys? Steps per mm for belt = ( motor steps per revolution * microstepping ) / ( number of pulley teeby fujisama - Huxley
It works ! The first problem was issue to a short which burn ftdi, atmega and one stepper stick... With my new sanguinololu, the problem was from marlin firmware. To fix this I took it on reprappro github, and inverted X axis motor polarity and now it works ! (I don't really understand what was the problem) PSU problems was a wrong approach, those I tried where undersized (300W ??), that's whby fujisama - Sanguino(lolu)
Hi, Could we imagine to replace the extruder by a duel extruder on reprappro Huxley ? Did someone try something similar ? I would like to use PVA soluble material to build supports. Fujiby fujisama - Huxley
Ok, I think I have a shortcut on my new sanguinololu board... I would like to try my Huxley with RAMPS 1.4, but I am scared about marlin configuration. Is it easy to change from sanguinololu to RAMPS 1.4 with a reprap Huxley ? I'm scared about SD card reader, heatbed control and non convetionnal dimension of Huxley's bed. What do you think ?by fujisama - Sanguino(lolu)
Hi Aris, I tried to use my multimeter to measure amps like this, but the meter consumes too much energy (extruder's fan runs slowly). I also try with another old computer PSU ATX (350W), but when I connect it to my board, PSU stops (it's very old, maybe it could not suplly so much amps, even with 350W)... Pfiuu after buying a new sanguino + atmega and 4 stepper controllers (recieved today), Iby fujisama - Sanguino(lolu)
Does anyone know why my motors don't want to initialize (Pronterface blocks on "connecting" and there is no motor noise at this step) ? Do you think, it'a a problem with atmega, or stepper drivers ? . thanksby fujisama - Sanguino(lolu)
Hi everyone, I'm asking for help. I can't drive any stepper motors on my reprap I built my reprap Huxley from reprappro two years ago, and it was working well. Since THE day. I don't now why, maybe the heabed regulation was defective... I think that a surintensity destroyed my atmega, then it was impossible de communicate with it. So I bought a new sanguinololu 1.3a assembled and tested to prby fujisama - Sanguino(lolu)
