yes, we are doing this.by baslisks - General
It was firmware settings I had set way too high. Looks like had put a 0 on my z axis, as in, instead of moving a 5mm/s it was moving at 50mm/s causing it to freak out. My printer is working now. I am a couple points of mm off from near perfection. just tuning now. Nice straight walls with very little extra plastic.by baslisks - General Mendel Topics
the problem isn't drivers it works if I give the commands manually but if I run a print I get a problem. I think I need to mess with some preferences. should be good tonight.by baslisks - General Mendel Topics
back to the buzzing stepper motors on the z. I think this is an alignment problem. Walked away from it before I broke something. Will come back into it tuesday.by baslisks - General Mendel Topics
Stripped my x and y axis down and rebuilt them. Ran some tests before rebuilding though, both motors are turning fine. After rebuilding I played with tension and current on the stepper drivers, fixed my stuttering of the axises. I have not printed again as I was too tired. I will set up this weekend and do more tuning, I lost my firmware settings I had but I can probably get close to them fairlyby baslisks - General Mendel Topics
alright, I did more trouble shooting. It may be the motor. The motor stalls and the stepper driver does not. I need to pull the motor out and do tests. Maybe swap x and y and see how they fare. If it is the motor do you think I can swap a z?by baslisks - General Mendel Topics
alright thanks for the info. new problem. My axis on that moves left and right on the z axis part has prblem when reverseing. It doesn't look like it is a belt problem it just doesn't move when reversing. I don't know whats happening with it.by baslisks - General Mendel Topics
I recently set up a prusa and am having problem with my z axis. The motors just sit there and chatter at me bu when I run them seperately they are prefectly fine. I have messed with my current settings on my potentiometer on the polulu driver and they don't change their functionality. I don't even have them hooked up to my z axis anymore and they still chatter. I do not know what is the matter.by baslisks - General Mendel Topics
Is there an easy way to do that in code though? I was thinking about this the other day and mayhaps we can build a slic3r or skein engine that lets you define fill by a function of some sort. maybe a function to an edge of the object or just a gradient from z a to z b. Would the programs freak out if you had to change the fill setting for the slice for each section?by baslisks - General
Just for information how the problem with extruder was strangely resolved (may be it can be useful to someone). (beginning of the story in ) After 3 jams of the Teflon barrel, it was damaged so that extruder would not hold extruder screw, to fix the problem I had to create a metal scaffold to hold extruder barrel and used Teflon plumber tape for insulation/tension. When the extruder started toby baslisks - General Mendel Topics
if you are in kansas city you might want to check out ccckc know they have a couple of printers they can help you with.by baslisks - General Mendel Topics
You design the thing so the seams are a feature of the object and not a distraction. Course it is awesome to build big things but we can achieve so much with the small. Plus, who cares what your printer looks like as long as it works well?by baslisks - General
The part can look fine if you do it in pieces. here is skimbal's portfolio on thingiverse. those are multipart pieces that look wonderful and are usually larger than the build volume when completed. I have seen other people print and assemble his work and they still look pretty damn good so it isn't so voodoo that he do but just good model design. The structural integreity of a shape that iby baslisks - General
Thats just means you have to design some way to make it fit. If you truly want it you can make it fit and work. You can build the parts up from smaller aseemblies, it may not be ideal but if you want the reprap to print itself, there are going to be parts that you will have to segment. Maybe we need to origami some parts and figure out some new beautiful tricks but You aren't going to solve theby baslisks - General
yes. is it easy? I do not know. maybe hard ware changes, defintely a software change.by baslisks - General
still looking for the facilities to do this. I do not have the tools needed.by baslisks - Powder Printing and Selective Laser Sintering
I would imagine the ball bearings having better cold resistance than the plastic. I could see them picking up heat from the container quicker too. I'll see how much it costs to get a ball mill set up like that and maybe run some tests.by baslisks - Powder Printing and Selective Laser Sintering
I have access to a liquid nitrogen dewar. Think if I dumped that in with some plastic and ball bearings that could work?by baslisks - Powder Printing and Selective Laser Sintering
do you know if they have better build logs on the .org rather than the wiki. Not turning much data up on their powder distribution.by baslisks - Powder Printing and Selective Laser Sintering
My current idea is to make a container that pushes up while I take a laser and sinter the plastic. after that layer is done move it up some . of an mm. distribute powder and repeat. I can build the xy part easy and probably the z. stuck on the plastic supply and the distribution of the plastic so that it is uniform.by baslisks - Powder Printing and Selective Laser Sintering
Already mess around with a repstrap and have that printing fine but I have been looking at doing more complex models and I want to try doing some SLS stuff. Been poking around but haven't found much on the topic of someone building one nor supplying the plastic. Anyone built one here?by baslisks - Powder Printing and Selective Laser Sintering
