True. I forgot about the stories I've heard where it turned out to be a library computer that got banned and it caused a lot of users to get excluded. My bad sorry.

I'm not sure about this forum software but on others I have seen the possibility to IP ban individuals.

QuoteNot so much with PLA. This is because the design does not work with ABS not cause you don't want to focus on it. I bought a J-head Lite back when was actually stated that it could print PLA without the suggestion of using oil.

Adjust the pots on your stepper drivers. It's possible the pots have developed resistance.

I like how it looks like it uses drawer slides for the axises.

Re: salvage build - 12 years ago

It really depends on what you want to build. Since you are scavenging parts you might look into repstraps. I think a couple of them are built from multiple paper printers. I've also seen homebrew hot ends as well.

Doh! That makes perfect sense and possibly explains my issues with my extruder motor having to have it's retraction speed cranked down really low. Thanks!

Re: Z steppers interfering with each other. - 12 years ago

What are the torque requirements for a Prusa i2? I'm curious if the Z steppers aren't torquey enough. I bought my steppers in a lot of 5. The sticker says: 16v 1.2A 1.8 degrees / Step Japan Servo Kh42jm2b140c It's a Unipolar stepper

Re: Z steppers interfering with each other. - 12 years ago

1) All seems to be ok. 2) The connections seem to be pretty solid. 3) Individually the motors work fine. But when connected together they seem to fight each other at higher speeds. 4) I'm using Ramps 1.4 running Marlin. I'll look around for some testing firmware. 5) I've swapped the drivers out with 2 known working ones. I think the steppers I have are just really electronically noisy. When

I've tried that and I've tried swapping the driver out for another as well.

Z steppers interfering with each other. - 12 years ago

So my Z steppers have started interfering with each other. At first I thought they were slipping but upon further inspection I noticed that one will stop moving altogether. It almost seems as if they are getting feedback from each other when moving at faster speeds and sometimes randomly at slower speeds. I've tried wiring them in parallel and in series. When in series one stepper will just s

Re: Printed Cubes bowed in. - 12 years ago

I figured I'd give an update. I've fixed the issue! Turns out my acceleration was too slow. I sped up the acceleration and the extra deposits on the corners ceased to exist. I'm rationalizing it like this: Since it would take it a relatively long time to speed up just to slow back down to get from one side to another it would spend more time at the corners than it would on the sides of the pr

Well I'm getting closer. It seems it might be a combination of issues. But little by little I'm getting it to look better.

This is the bed: The top portion of the bed is a piece of thin plywood with back support of balsa to make it sturdier suspended on springs. The glass is held to the top of this by binder clips.

Re: Printed Cubes bowed in. - 12 years ago

Just ran at 10%. It does appear to be printing straight (no two axi are moving at once unless it's doing infill so I'm assuming it's not doing it). My fan kicks on right after the first layer. Could that be the cause? EDIT: Actually on second thought I'm not ruling the frame out just yet. Since it's at a slower speed it's possible that it's just printing straighter due to less force behind

Re: Printed Cubes bowed in. - 12 years ago

It was suggested on my reddit thread about this issue that it could be my machine warping. I replaced the bed since its alignment was off and remeasured the spacing of the Y axis. I'm still getting warped parts.

Re: Printed Cubes bowed in. - 12 years ago

I've tried recalibrating my extruder (It's a Greg's Hinged Accessible Extruder) and I just want to confirm my math here: I have RAMPS 1.4 set to the default 1/16 steps driving steppers that require 200 steps to go completely around. The gear set is 47:9 Fishbone gears and the effect diameter of the hobbed bolt is 6.54. So... (200 * 16) * (47/ 9) / (6.54 * pi) = 813.76298 I am however still getti

Re: Printed Cubes bowed in. - 12 years ago

It's the slicer. Cura for some reason does this to my prints but Slic3r does not. Correction. It doesn't do it as bad with Slic3r it's still happening but more so on the top than the bottom.

Re: Slic3r infills wrong areas - 12 years ago

I've had this issue off and on. Usually I have to delete the profile used for the printer and recreate it.

Re: Printed Cubes bowed in. - 12 years ago

For a 30mm cube corner to corner is 30.40mm and side to side is 29.73mm. I'm currently using Cura but I'll switch back to Slic3r to see if it's doing it now as well. (I don't remember Slic3r doing it but I'm just now noticing it happening)

Re: Warts on print - 12 years ago

The location of those make me think it's the hot end leaking a little bit as it makes its move on the Z-axis.

Re: Printed Cubes bowed in. - 12 years ago

I'm still messing around with this. I've tightened the belts further but so far haven't had much luck. EDIT: Would a XY Jerk setting of 10 cause this?

Re: Printed Cubes bowed in. - 12 years ago

I'm printing 1.75mm pla with a fan. The infill on this particular file was 25%. I've done other cubes at different infills but most have this same issue. This particular one is rather flat but the others are actual cubes.

Re: Printed Cubes bowed in. - 12 years ago

Sorry my camera isn't very good at taking pictures.. As it is moving in from one corner to the next it appears to bow inwards making a parabola between the two corners.

So I've recently noticed that when I print things with flat sides like a cube they curve in slightly making the corners of the cube not 90 degrees. Any idea what causes things like this?

Re: The J-Head Lite will blow your face out - 12 years ago

Got mine today. It's the prebuilt version if that matters. My first impression is that it's very well built. It heats up like a champ and the temperature seems fairly accurate. I do suffer from being unable to reliably extrude PLA though. From 180 - 210 I was still getting jams. When the jammed filament is pulled out it looks to have melted/deformed in multiple locations and not just at the

Re: The J-Head Lite will blow your face out - 12 years ago

If it's melting in the chamber you can use a small fan to lower its temperature. That might help with some of your jamming issues. Edit: Since this is literally a threaded rod washers and bolts could be added to act as heat sinks.

I ended up recloning the Marlin from Github and reapplying my configuration settings (and lowered the jerk settings a little) and now my cube is only .01mm off in both directions. I'll accept that
