Everything is working great now... took my build times from 2 hours to 26 minutes. And looks good. Onlything left to figure out is the head over shoots on 90 degree angles just a tad and rounds out corners a bit... other than that it's awesome. Chuck

I tried disabling the feature but then the heads mashed past the endstops. I'll take a look at your SF though, Thanks!

ok.. so far so good. The firmware works. You have to enable Dimension in SK for it to extrude. (this is new)... I can jog and shuttle around and set the zeros. Thanks! Of course I have another question.... Speaking of extruder the head cleaning move at the beginning of a print goes like a bat out of hell and chews up the filament. Where would I adjust that, in the firmware or SK?

How do you access SK44 from RepG? Or will it only run from script? If it can be run from RepG how do you install it? I can't seem to find info.

I'll give it a go. You rule... thanks!

The current one up on the net is ErikZalm-Marlin-157aa7f Can you put yours up on Dropbox or something for me to give it a go? That would be huge if you could. I have RepG26 and SK 40, If I could at least get on the same page as someone else that is having success that would make it easier to trouble shoot. Chuck

Can someone tell me where and what the modules in the firmware upgrade URL are? http://firmware.ultimaker.com/ultimaker_firmware.xml They just say MArlin build 1 and Marlin build 2 Using RepG to update the firmware just for the hell of it tried out the Marlin builds there. Ver 2 doesn't have the issues I am experiencing with the build pull from Git. They do however have virtually no Extruder feed. (which I was instructed was a problem with Marlin and had to fix in the configuration.h. Being this is a binary pull down I can't get at those files to compile them

I don't suppose you have a copy of the build that works on your machine avail would you? The one that is linked to on Ultimaker's wiki is the one I am not supposed to have. The one linked to in this thread is the one with the stops issue. https://github.com/ErikZalm/Marlin The Sprinter Firmware won't run the the extruder for some reason. It would be nice to see what other people are running in a what combination... like which version of SK with which ver of RepG and which firmware, and a complete list of modifications to those modules. I am finding all kinds of blog entries. For the mean time I am trying to get my machine back to it's "factory state, this upgrade has has been way less than easy. Thanks for the help... hopefully someone can chime in and I will give it a go again. Chuck

I Installed the recommended version.... I can't get it to do much of anything. (I set the baud rate and made the recommended changed to the config file) First thing I noticed is it won't let me jog to a negative value so the print head is floating in space and I cannot jog until I hit the end stops and make the current position 0,0,0 Second thing is when I send it a job it just pulses the z table. For those of you that have gotten this to work what were the exact steps? Or maybe someone can send me their Config files? I am losing my mind.

ok... nothing I do is changing the feedrates. I am going to go to the older sprinter firmware.

this is the version I am using https://github.com/bkubicek/Marlin Where would I find older versions? turns out it was pulling older Gcode files. The new Replicator names the files with a "export" in the name. Pull pulled the old gcode files when I hit the build button. If I load the export versions and go to edit->build it goes like a bat out of hell and now I can't slow it down in the feed rates. trying some more experiments.

Ok... here are two different gcodes... same model with different feed speeds.... but they print the same speed, the fast one just one dumps pla and jams up after a while.

So the cool module should be set to Orbit or Slow down?

I upgraded to Marlin and RegG25 can't seem to get it to go faster using SF 40. I have been adjusting the feed and flow rates and nothing seems to be going faster. Also the new default PLA has some odd numbers in it. Default feedrate is 16 and flow is 210. (PLA) I have the machine running smooth now, printing consistently good. Now I want to start cranking up the speed. Also I downloaded a fan shroud from Thingverse and for some reason this is the only model that won't let me build. It did cough up some warnings so I cracked open the file in max and cleaned it up a bit. Generate Gcode and Replicator G won't let me build it. Can anyone else get this thing to fire off? Or is this a SK 40 issue? (see attached) Chuck

Does the machine make a "grinding" noise when operating? Mine couldn't handle the speed and was jumping the belt on the Y axis... the belts were pretty tight too. The newer machines have a torque-y motor. I ended up taking the machine apart and polishing the brash bushings inside with 320 grit wrapped around a dowel. It should slide effortlessly . I also removed the "sticky" lube (which will get WAY worse in cold weather) and used a sewing machine oil. I am still trying to find the sweet spot with Marlin... Good luck!.

everything worked, has crazy speed now and my machine couldn't keep up with it. The y axis was catching (it was always a little stiff). The brass bushings never really slid nice on the shafts. I took the machine apart and polished the insides of the bushings with 320 grid sandpaper wrapped around a dowel. Got it to the point where it would slide if you tilted the shaft. Now every thing is working. I need to adjust all my settings again to get smooth prints. Some of the models won't enable to the "Build" button after generating Gcode. Need to figure out what that is. Chuck

yeah that was it. The instructions said pull down the latest, didn't think to try the alpha. It has been uploaded... going to give it a shot now. thanks! Chuck

Does the same thing with the Sprinter Verify

I am currently trying to install Marlin to help with communication errors. I am getting the current errors when I click the verify and I get the following errors. (see attached pic) I assume this isn't what is supposed to happen correct? Chuck

Yeah I think I might have to do that. I am getting some awesome prints now with a minor issue on start up. Every print is doing a slow 10 second or more head move dumping (not feeding, just running out the nozzle) the entire head of PLA out before it starts printing so the first row of a raft is non existent. I am trying some lower temps so maybe the head wont evacuate before the real printing starts. I am also looking into editing the GCode to eliminate what ever move that is... or maybe there is a good reason it does that? I am hoping the firmware and SF update will give me more control and a better idea of why it does what it does. Thanks for the help guys!

The stepping on the z motor was set to 1/16 instead of 1/8 so all my prints looked like you took the model and squished it in height. A 20x20x20 mm block ended up being 20x20x10. The print quality was very good though. I fixed the stepper jump and it never printed right again. I spent about 3 hours last night messing with feeds and temps. It was almost like the z was way to high for the next layer to reach it by the time it cooled. Thanks for the Carve tip... I'll give it a shot.

The first successful prints I made were made with the steppers set wrong on the PCB. It was printing everything scaled half height. Now that I have that fixed I can't get anything to print correctly. I need to double the number of slices in Z but can't find any settings in Skeinforge to do so. Still using the firmware that came with the machine... Chuck

After spending quite some time getting my machine working I just wanted to share some learns. LEAKING: The instructions specify the use of teflon tape (mine unit came with a little ribbon of the stuff) After developing leaks I tried reapplying the tape and ended up with some of the same issues. I suggest using an automotive high temp liquid sealant like Permatex High Temp Thread sealant. Way easier to use and works at temps in the 400 degree range. http://www.permatex.com/products/Automo ... ealant.htm JAMMING: As for the head jamming the instructions specify setting the feed and speed to 50mm. This caused all kinds of issues for my machine. I suggest starting at half that and increase from there. Also I found I needed to run at 260 and turn off the auto temp in the Gcode creation settings. When I ran into jamming issues I cut the feed tube's mangled end and must of got some of the tube end in the nozzle because it was jammed up REAL good. To clean out the nozzle I took it off and heated it with a propane torch and blew it out with compressed air. (from both sides) Worked like a charm. I also needed to clean the PEEK adapter of PLA residue. Did the same thing, lightly heated with the torch and blew it out. Currently printing my first successful print... I'll try to add some additional things I have learned as I go. Chuck
