What version of Java is installed? What version of RepRap host are you using? I think I remember getting ringGet errors when I had M or G codes that did not jive with RepRap host software. Not sure how that relates to the host software causing these errors though. To get my electronics and software in sync I would power up the mendel, hit the reset button on the motherboard, hit the reset on theby steveo290 - Reprappers
Is there a led light on your endstops? Gen 3 electronics have a green led on the endstops when they are powered on and nothing is between the uprights. Might need to check the z axis endstop wiring or perhaps swap endstops to test. Good luck.by steveo290 - Reprappers
Is the led for the thermistor on the extruder board (TZ remix v2.2) supposed to be on steady during printing, or flashing once in a while? It is on steady during the heating ceremony but goes off once it starts printing and I see the heating led flash once in a while. I just want to confirm normal operating procedures, thanks.by steveo290 - Reprappers
You may not have to modify your firmware steps per mm. I have a 10 mm gear on my extruder motor which I found to be like .113 steps per mm when using a formula found on the wiki and here on the forums. I used that for a while but when I switched to using SF instead of the host software for g code generation I was told by Emt that the best way to use SF is to set your feedrates and flowrates (extrby steveo290 - Skeinforge
I would recommend going through and configuring everything yourself. It takes a while but you end up with a ton of more useful knowledge in the end. Learning g code has been super helpful in my reprap learning. I had similar problems when I switched to SF. If you are working with PLA then turn off the chamber and cooling. Also, set your x y feedrates and flowrate to the same number, mine is 25mm/by steveo290 - Skeinforge
I have had success with .36 layer height (I think default is .4). .32 might be a little low. I also do not have my z0 set to absolute 0, extruder touching the bed. I have my extruder Z0 set to like 1-2mm off the bed. my heights go as follows .18 -> .54 -> .9 -> 1.26...by steveo290 - Skeinforge
I had a similar problem before and found that I did have a short between my nichrome and my thermistor. Then another one when the bulb on the thermistor would get twisted, creating a short with the thermistor leads leading to the bulb. My solution was to take the thermistor off, lay it out flat in a v shape and put some tape on both sides then reattach it to the barrel. But only attach it with aby steveo290 - Reprappers
hmm I was using crimps I salvaged from a 8 pin header from a computer cable (additional usb extender or something). Did you guys do anything special to the wire? I think the type of wire I am using is burning up and charring, which reduces the connectivity.by steveo290 - Reprappers
Tom, I had this problem for a while. Here is the sequence to follow. Get your code ready to go. Press and hold the reset button on the extruder or motherboard depending on which one you are using. Then click the upload button. Continue holding the reset button until the white text comes up in the Arduino window. This should work every time. If it does not work then it is most likely your cable yoby steveo290 - Reprappers
What kind of tips/tricks do you guys have for connecting the nichrome wire to the leads going to the extruder board. I have been using crimps and ribbon cable wires. It works but after a little while the connections fail. I think there is residue building up inside the crimp connection and gradually worsening the connection. I then have to take the extruder apart and replace the wire and crimp. Wby steveo290 - Reprappers
Ok thats understandable emt. Last night I spent my time rewiring my heating element and thermistor. Did a few tests but only the last few lines actually extruded anything. The filament was 'leaking' out the hot end pretty rapidly during the heating ceremony. So I am thinking there could be something wrong with my thermistor. Still reads at 190 and the thermistor is right against the barrel, justby steveo290 - Skeinforge
Ian, yes 5% increase on the step per mm would be .5775. I was adding 5% of 1.00 to the steps per mm, not 5% of the current steps per mm (.55). But adding 5% to the current steps per mm is a better idea I think. I purposely didn't have extrusion on the y moves, just to separate lines easier. It might be better for the test tho if I have it continuously extruding. Like a raft almost. My g code gby steveo290 - Skeinforge
Recently Emt mentioned that for ease of reading g code that I set my skeinforge feedrate and flowrate to the same number. I had originally configured my extruder's firmware to be .1131 steps per mm, as per a formula I found on the wiki and numerous posts by other users. That would allow the Reprap host software's default 3000mm/min to be a good starting point for extrusion speed. But I switched tby steveo290 - Skeinforge
I did end up getting another tech zone. Figured I should stick with what I was using already to avoid compatibility issues or anything else. I am happy with this method as well. Still trying to calibrate though. Just can't seem to get it dialed in correctly. I get it close and change one little thing, then suddenly its completely wrong and prints garbage. I go back to the old settings that kind oby steveo290 - Reprappers
I believe this was fixed for me when I disabled acceleration in the firmware. Running 5D firmware also.by steveo290 - Skeinforge
Edit: I figured out what the problem was all along, I needed to get rid of all the M101 and M103 entries. There is a php script to make skeinforge gcode run on 5d firmware. I got php installed and ran that script, it just spit out a file saying that I didnt have a default .settings file and didn't have any gcode in the file though. So I manually removed the M101 and M103's for the first few layerby steveo290 - Skeinforge
Yes I understand how SF and RR host work. Earlier I meant that if I create g code with just the RR host. Like increasing the infill density. There is just a variable for number of bottom fine infill layers and top fine infill layers. How did people make solid parts before skeinforge? I can attach the SF'd g code later tonight. thank you. EDIT: I attached the g code for the cube that I made in Sby steveo290 - Skeinforge
This is the cube I am trying to print and getting blobs. Tonight I am going to try to do the manual g code sending via a terminal program. It is possible that my extruder isn't configured 100%, but the lines and infill it does lay down in between the blobs looks decent. I also installed Ubuntu 10.4 on my spare laptop and am going to get RR host and Skeinforge downloaded to it today at work. Iby steveo290 - Skeinforge
Yeah I had Java 6 installed, so I installed Java 5 and the same exact thing is happening. I will just go ahead and install Ubuntu on my laptop. It does look like timing issues Emt, lines keep getting requested to send again over and over. Hopefully linux will solve my problems... hahaby steveo290 - Skeinforge
I won't know what version until later tonight when I get back home. What version(s) are stable?by steveo290 - Skeinforge
Yes I am using windows xp. Anyone have SF, RR host and windows xp success? I will try the terminal command idea tonight. Perhaps install a linux distro on my laptop as well. Thank you.by steveo290 - Skeinforge
Ok thanks Rhmorrison, turning acceleration off solved the problem of the inline feedrate commands not being obeyed. I still am getting the blobs when i do the 20mm test cube. I tried to do the test to calibrate my extruder, doing a G01 X100. E100. // Move X 100mm and Extrude 100mm But my extruder did not even attempt to turn when moving. Not sure why. I also noticed that i am getting a lby steveo290 - Skeinforge
Ahh yes I should have known that. I was thinking it was an acronym for something in SF. Thanks. I am going to try that right now.by steveo290 - Skeinforge
The dimension plug in was activated. For clarification though what is FW? Thanks.by steveo290 - Skeinforge
I saw a post from a few months ago saying that it is not possible to adjust the infill amount for printed parts when using RR host to create the g code and do the printing. Is this still the case? or is it just difficult? I tried to adjust the number of fineInfillLayers for the top and bottom but that didn't do anything. Do I need to turn on the support material parameters and adjust them, makingby steveo290 - RepRap Host
Ok found the problem. I believe this follows along the lines that skeinforge does not work with RR host software. The problem was that I had been manually implanting a G1 F30.0 right before my Z axis moves. I was just hearing my z motor make a loud zzzztt noise when it was supposed to move. I think the RR host software is ignoring the inline feedrate command in the G code. So I had manually set tby steveo290 - Skeinforge
I got the newest skeinforge working with RR host! I had to turn off the heated bed plugin which is fine since I no has a heated bed.by steveo290 - Reprappers
Nophead, Thank you for the response. When the machine comes back from its heating ceremony it does move out to X-8.92 Y-8.92 and the speed is fine, then it sits there and prints the blob. I think that I just am not waiting long enough for it to start moving again. Its going from 0 - 60 units extruded in one line, which seems to be like a lot. I usually just shut the machine off so I dont wreck orby steveo290 - Skeinforge
Ok splodge was not activated. That would mean even less would be extruded over all. So it looks like this is not where the problem lies, correct? Here is the first part of my gcode where the outline is supposed to be done (only first few lines), notice the large extruding amount compared to the section for the infill M101 G1 X-8.92 Y-8.92 Z0.2 F1500.0 E60.408 G1 X8.92 Y-8.92 Z0.2 F1500.0 E188.by steveo290 - Skeinforge
