Recommend Octoprint for Raspberry Pi. I have Octo running on Mark I rasp pi over home network (LAN). Am running latest version of slic3r on newly upgraded win 10 laptop - there is the option to flick it straight through to the RaspPi Octo server in Slic3r. You then access octo control interface through browser - you just click print and watch the magic. Really is TOO easy. My previous workflow waby aegis1980 - General
answering my own question.... I missed this webpage: reprap.org/wiki/Printrun#ubuntu If you go down to connection failed with printer section and run patch... TAAA DAAAA - issue fixed.by aegis1980 - Reprappers
Hi, I have had an i3 working well using Pronterface on Windows XP. I am trying to move over to Ubuntu but am having issues connecting to Reprap successfully. In Pronterface I am connecting to /dev/ttyACM0. Computer seems to know that reprap is there but htting connect brings back 'attempted to write invalid text to console' in Pronterface and not much else happens. I have installed Arduino stufby aegis1980 - Reprappers
Hey, I had this same issue. Posted a question on forum somewhere but not sure I ever got an answer. Hopefully what I ended up doing can help... After a bit of screwing around I found that my z-axis was missing steps so when the z axis should have been 30mm, say, it was physically at 25mm or so. I fixed this by lowering the speed of my z-axis in the config file - cant remember how but it worked.by aegis1980 - Reprappers
Hey, Thanks to all for responding. After playing around with temperatures etc etc I found I had a more fundamental issue with my z-axis missing steps here, there and everywhere. Slowing things down, heat sinks on my drivers and turning down the current seems to have fixed things. A new (previously hidden) issue seems to have arisen now though. I have calibrated the extruder feed rate...so 100mmby aegis1980 - Reprappers
Hey All, I have managed to get 'a result' from my reprap i3 but I am wondering whether anyone can help me diagnose the issues I am having...and hopefully suggest some get-outs. I am trying to get things working using this model - a stack of 5mm cubes. I do not have a cooling fan. In a nut shell: [1] Cube layers start at 5mm high (as they should be) and get progressively smaller as print proceedby aegis1980 - Reprappers
Jumpers were it!! I had none on RAMPS 1.4 so drivers were working at '1 full step'. Have raided various computers for 12 jumpers and stuck them in. Everything works nicely now on Reprap front...not so good for computers but hey Now to seemingly underpowered heat bed...by aegis1980 - Reprappers
Hey thanks, I'm just concentrating on the X and Y axes for now. belt and gears: 2mm pitch gears: 20 teeth steppers: 1.8 step angle The electronics hardware I have is basically this set According to this gives me 80 steps per mm - this is what I had in my config (as DEFAULT_AXIS_STEPS_PER_UNIT). Where is a 'unit' defined? Not sure I have seen steps per millimeter in settings in Marlin's confiby aegis1980 - Reprappers
I have literally just now tried an XBox360 203w psu on RAMPS1.4 Prusa i3. Motors work and extruder heats up fine but my (mk2b) heat bed seems to be struggling to get over 75 degrees...which is a pain. I was planning to use ABS. I've read that sticking some insulation on base can help. Might try that...by aegis1980 - General
Hey all, I am at a point where I am trying to get the various motors to run smoothly on my Prusa i3. In pronterface, if I type in the gcode g0 x10 I am of the understanding that my x-axis ought to move 10mm (or so, pre-calibration) right? I am finding though that it moves around 70mm or so. I think related to this - if I set the rate at 3000min/mm my motors struggle to get anywhere despite puby aegis1980 - Reprappers
