Welcome to the SeeMeCNC Community

Well, mine just started stopping mid-print. After about printing for 2 hours, the carriage stopped on the print, heat and bed on, g-code flashing through the log window [Repetier v0.85b with Polygonhell's firmware]. I paused the print and there is no command over the motors, just seeming dead. Have ...

I'm pretty sure the issue is having the head meet significant resistance and the drive pulleys eating the belt. Almost all the failures seem to be about 1/3 of the way up on the front side of the pillars when the head is homed, that's more or less on the pulley with the head on the bed. Which to me...

I just lost one of my Rostock GT2 belts. What are the advantages of the new 20 tooth plastic pulleys? I've had some issues with the black dust and I wonder if the new ones will cut down on the abrasion. Any one have thoughts?

Thanks.

Thank you for the input.

I'll work on it. I'll try something with a credit card wedge. If I could, I'd print something

Hi Mhackney - What have you discovered is the easiest way to up-snap the rods from the aluminum u-bolts? I'm in the same place now, realizing I have to very carefully fit the mating surfaces. I have to smooth everything out so I'm loosening the screws that hold the axles on the cheapskates and slidi...

So far I've made 3 prints. The one on the left was the first which I killed when it got so bad, the one on the right I let run to completion, then I lubed the joints and got the one in the middle [still attached to the glass build plate]. There are still infill problems, but I've got something that ...

Things are improving. I'll post some pics on the Checking Extruder thread later. I applied a small amount of grease to the axles, aluminum connectors and rod ends at the carriage and cheapskate, smoothed everything out. Now, I'm trying to figure out how to get the belts to ride in the center of the ...

Hey, I haven't given much thought yet to just how to add some lights, it's just that it is sometimes hard for me to see. I've also thought about shorter spacers so there was a little more room below the carriage. I tried a slow print and it was worse, more like spaced beads rather than a continuous ...

And, I did change the first layer to .4 and the following to .3, but that didn't do much. I'll slow it down. Could backlash have anything to do with the shattered appearance when it starts to make the towers on the hollow cube? I think I'll snug up my belts and look over the cheapskates for wobble. ...

I have not grabbed my torch and a dish of flammable liquid. The tube seems OK, I'm extruding again at 234 now without the little washer. I tried another print and got much of the same mess after awhile. Any thoughts? Do I try it with faster feedrate or slower print speed? Or...? I think someone else...

That's why I asked. And I guess it is rubbing alcohol, but...

This looks like nozzle flambe. I'll try it with the torch sometime.

How do I tell if I have totally FU the PTFE?

Thanks, I'm sure there are multiple factors. With the blowtorch cleaning. I saw a youtube video that has the guy heating it and then dipping the nozzle into alcohol to cool it. Do you do that? If so, what do you dip it in. I took the bowden tube off at the extruder and tried pushing filament by hand...

I have been practicing the nozzle cleaning process, acetone, a big pin and a single strand of wire. Has anyone tried the blowtorch method? Now, using the window tint, which was pretty easy to handle, I got something. [img]http://www.craftgizmos.com/rostock/cube1.jpg[/img] The first portion looks pre...

Yes, but I'm not sure exactly where to measure what on which scale. I did do the tree yellow and three black wires from the power supply to the RAMBo, there's a picture on my build zone thread.

I'm having a related issue. My Rostock Pheobe beds heats, but it doesn't get above about 88 centigrade, and the red light from RAMBo is always on. It just doesn't get hot enough, so if I really need to get to 100 I can't now. My house is at 65 fahrenheit FWIW.

IT SQUIRTS!! I had some trouble getting it to extrude, turns out I hadn't tightened the big bolts through the bearings on the extruder so things were slipping and I wasn't getting good traction on the filament and consequently ineffective control. Moving onto the final steps and test printing. I hav...

g. - in the manual for the red cube print there's blue tape on the bed and from what I read you were heating the bed to 55. Right? I'm sure I'll understanding more once it starts printing. I just want to see the thing squirt.

Thanks.

I had a little trouble getting tension on the belts so I did this. [img]http://www.craftgizmos.com/rostock/u-bolts.jpg[/img] Getting some u-bolts from the hardware store, I used just the socket end only [shown on the right] with my fingers to adjust the tension so it isn't super tight. Kinda clunky,...

Thanks, I went out and got the glass plate. So when I set the Z axis, do I do it with the blue tape on the plate, and with the bed heated? How much force should I use to burnish the tape down onto the glass surface? I tried that on the plastic plate and it seemed OK, but when it cooled the blue tape...

Well, I'm almost there with the Rostock MAX. Heat bed works, hot end heats, motors and belts seem OK. After trying a few times and watching that plastic plate move while it is heating I'm going to get a piece of glass. The question I have - what code can I use in the manual Repetier window to get th...

Thanks g, Why didn't the limit switch stop the travel? Did you find telltale black dust in the niche where the toothed pulley lives? I didn't let mine go on for more than a second or two, but I was surprised it happened. John? And, can you further explain the issue of a vacuum cleaner and static ele...

I got my split flex and RTV at Autozone if there's one near you. I got a green LED from a local electronics store.

I've gotten my motors working, but can someone please explain what I look for/listen for to see if the motors are slipping? So far I've had one issue when I clicked the wrong Z arrow button in Repetier and the z carriage moved up against the limit switch and kept running. Haven't figured out why tha...

I tried to see if I had gotten everything with the motors and belts right before I had completed the hot end - John says the hot end therrmister wires need to be in place or I'll get an error? Well, so I'm finishing up that part. Does this look OK? [img]http://www.craftgizmos.com/rostock/hot-end.jpg...

I understand about the cost factor. Mine was about $16.50 including tax, less than scotch, so I didn't think that was too bad. For me it was a big help. Maybe you could put it in as optional? Right now I'm having issues with repetier, I have to make the hotend, and my not knowing enough. Happy New Y...
