@Dust, Thanks for the reply! I'll give that firmware a try, and I used to use Pronterface so that is nice and convenient. I'm surprised to hear about the 3mm going obsolete! Can you recommend a 1.75 extruder?by Adam.m.Nelson - General Mendel Topics
Hey guys, It's been a while since I've touched my Reprap Mendel (Same one as on the page), and I am looking to finally get it up and running. Last time I touched it I was having firmware problems (crashing into the frame in when homing, but ONLY during prints), and we ended up stripping the hot-end. So I am going to try again. I've been reading around, and the market space has changed so mby Adam.m.Nelson - General Mendel Topics

Hey, thanks for the response. Yeah I have both end stops set-up, and they are responding to the GUI (at-least manually, and with the home command). I'll look at them again tonight after work. I did notice that either end-stop being actuated will satisfy the home position, is that normal? The weird thing is that the HOME command and the "move to 90 mm" (aka near the centre of my print surface)by Adam.m.Nelson - General Mendel Topics
I tried posting this in another thread, but got no love. Thought I would try it here. Hey guys, I gave up on my Gen3 electronics and bough a set from ReprapDiscount. Everything is calibrated, and seem right (everything works manually). However, when I try to print a test cube the X Axis drives itself into the end block (This is after its already homed all three axis successfully). I narrowed theby Adam.m.Nelson - General
I tried swapping the motor wires around and the HOME command and the "G1 X90.930 Y91.110" Command both send the print head in the same direction (regardless of the way I have the motor plugged in).by Adam.m.Nelson - General Mendel Topics

Hey all, it's been a while. I finally had time to look back at this printer, and I can't get NoobMan's code to compile. "Teacup_Firmware.cpp:3:22: error: WProgram.h: No such file or directory" From what I understand WProgram.h needs to be changed to arduino.h, but.... I can't find a reference to WProgram anywhere is his code. Any ideas? Edit: According to Notepad++ no files in the project oby Adam.m.Nelson - Firmware - mainstream and related support

@NoobMan Thanks for the upload. I should be done this product launch in a month or so, and I can take a look then. If you are feeling ambitious before then let me know and I will upload my filesby Adam.m.Nelson - Firmware - mainstream and related support
I've been swamped with product launches, maybe next month i can get to this. Has anyone had a look in the mean time?by Adam.m.Nelson - Firmware - mainstream and related support
I'm using the ramps settings in teacup firmware. Using skeinforge with the laser settings the slicing ends up using the same gcodes for as extruder on off, so I an just going to get rid of the step control there, and put "this pin on" "this pin off" logic in its place. I think I fried the original end stops somehow, not too sure, but I have the XY axis moving nicely, and the actual lasing seemsby Adam.m.Nelson - Laser Cutter Working Group
Hmm maybe I'll just stick to full power and faster move speeds. Did you have any issues with the Chinese end stops? I'm sure I wired them right, but they don't seem to work lolby Adam.m.Nelson - Laser Cutter Working Group
Oh, I talked to our optical engineer today, and he said PWM control would likely give good results with these lasers.by Adam.m.Nelson - Laser Cutter Working Group
I got the majority of the electronics and firmware up and running on a Mega, but I didn't realize that Skein forge still uses the extruder codes to plot the lasing. Is you plan to just change the on off for the extruder to control the laser?by Adam.m.Nelson - Laser Cutter Working Group
lol, yeah that's a good reason. I started reducing the latest teacup firmware last night, taking out all the temperature, extruder, and heater control. So far both axis are working, and all thats really left to do is fill in a G-Code handler that turns on/off the laser and i think we're set. While I am reducing the code I am using the Motherboard 1.2 setup, but will port it to the Atmega 328 aby Adam.m.Nelson - Laser Cutter Working Group
Yeah I got the steppers wired up last night, using an atmega328 to run them, it works great. The only thing I'm not sure of is if the laser drive is solid on, pwm, or frequency driven.. One of the guys I work with is a optical engineer, and we're going to go over it tomorrow. There isn't much to running the laser cutter, why were you thinking of an arduino mega? Is there a loading issue witby Adam.m.Nelson - Laser Cutter Working Group
Oh, yeah, good idea. I did notice that I had to copy in some extra files sometimes. When I get a chance to dig back into it I'll look at that too.by Adam.m.Nelson - Firmware - mainstream and related support
OK I think the issue is right here: Nov 17, 2011 Link to the Github page This commit will intermittently spin the extruder once then crash the machine.. dda.c: also reset startpoint_steps.E on relative extruder movements. … 1ee4668e21 Browse code Traumflug authored a year ago This commit spins the extruder... dda.c: fix a typo in update_current_position(). 64b1a23cd3 Browse code Traumflugby Adam.m.Nelson - Firmware - mainstream and related support
OK, I've narrowed it down to between Nov 12 and Dec 6 2011, the extruder spins on Nov 12; but on Dec 6, Nov 21, Nov 17 the machine acts kind of glitchy. I think I may have knocked a wire loose after my Nov 12 2011 test so I am going to go over the printer before I check anymore of the commits. But for now atleast the Nov 12 2011 was a working build, and I know the issue is between Nov 12 and Decby Adam.m.Nelson - Firmware - mainstream and related support
Ok I figured out how Git Hub works. So far this is what I've found March 03 2012, extruder won't spin, machine crashes. April 11 2011, extruder won't spin machine freezes. Feb 20/11, Feb 17/11, Dec 1/10, won't compile back to Arduino 018, i think these are a compiler issue, and Arduino 17 and before won't run on my Win 7 box.

mhm, so, when you go to a commit, then click on files, that's bringing you to the latest files again isn't it? If it is, how do you have to manually enter in the code changes?by Adam.m.Nelson - Firmware - mainstream and related support
Yeah I am starting to work through the commits on git hub now. I'll let you and the other gents waiting for this bug fix know if i make any progressby Adam.m.Nelson - RepRap Host
Oh excellent timing, let me know how yours goes. I'm going to start with an arduino and move up.from thereby Adam.m.Nelson - Laser Cutter Working Group
MyMaker, What are you using to control the axis? (on the electronic side). I am modifying a 40W CO2 laser I got that had terrible axis control and a garbage interface. I got the new axis working nicely, but haven't decided on processor/code yet. Any suggestions?by Adam.m.Nelson - Laser Cutter Working Group
Viktor, I skipped buying upgraded hardware for my mendel, and just built up some really nice stepper drivers i modified to work myself. They work great. Now I am looking to load some sort of G-Code interpreter onto the arduino and I am done. Can you recommend a firnware that can be made to do tis easily (maybe teacup?, 5D?) I'm currently using pronterface to control my Reprap, well i will bby Adam.m.Nelson - Laser Cutter Working Group
