Re: Machined extruder - 12 years ago
Thanx. Haven't seen that in years, is it related to "floor space"? Both seem to have that "space" thing in the name. Toddby tcoleman - General
Re: Tinkerine Studio - Ditto 3D Printer - 12 years ago
Ok, I don't know where I've been, but this is the first time I've seen a cam-lok on the pressure plate...... I LIKE that! Not too proud to "steal" that idea.......Thanx. Oh and I agree with nixing the wire ties I've done some crazy things with wire-ties including holding motorcycles together to get out of the hills but accurate cnc? As an old retrofitter it just sends creepies up my spine. Your mby tcoleman - General
Re: Skipped steps - 12 years ago
I have found that my machine run perfectly until a very certain type of structure is printed. It is when a solid base is printed for an internal structure. I find that Slic3r does a very short move, very fast zig-zag at the edge of the solid (usualy disk, base of a hole) insert. My X has a rather high mass and the extreme reversal/acceleration causes the loss of a few steps and it usualy correctsby tcoleman - General
Re: Slic3r 0.8.4 is Out Now! - 12 years ago
Excellent, that I understand. Did a test piece this weekend with several functions, outside size, inside size, diagonal size(square), bridging and a cone to a point. Bridging was amazingly perfect absolutely wonderful, the last one must have had a problem even NetFab didn't recognize. But inside dimensions are still way under sized almost 0.5mm or worse! The outside is fine and heights are fine.by tcoleman - General
Re: Slic3r 0.8.4 is Out Now! - 12 years ago
Well as for the STL's Netfab really seemed to like them .Said they were just ducky. Will have to set up a simple test object. As for the extrusion widths ..... as a % of what? In an earlier post (different thread) I was told that a value less than 1.5 ( 150% I assume) would cause trouble but If I want a .4mm extrusion width (.35mm nozzle) I would set it at 100%. There must be something I'm missinby tcoleman - General
Re: Slic3r 0.8.4 is Out Now! - 12 years ago
Are there any good (pref.offline, no net at home) documentations on the Slic3r advanced parameters? I have found nothing useful. and don't understand just what the "extrusion widths" are and how they are used or just how they effect the print. The official online docs have a big blank for advanced settings. Also hope they fixed the bridging. It should never stop halfway across a bridge, back up tby tcoleman - General
Re: It starts good....but - 12 years ago
I guess I'm not understanding how to calculate the parameter. I understood one took the width(.35) divide by height (.27). I wondered why one would not let the software calc such a simple thing...I guess it's because I'm wrong...Humm... How should it be calculated? Or should I leave well enough alone and let the software do it for me until I know what I'm doing? I have some ideas on checking forby tcoleman - General
Re: It starts good....but - 12 years ago
I started out with 1-3mm retract but didn't get half of my part. Then started cutting it down to what I have now. No stalling, if I watch the motor gear nothing is stalling or slipping. Will try to cut back my retract speed though just in case. Is the 'fast forward' you refer to the un-retract. if so there is no attempt to re-feed much less stall. As for the extrusion width, the parameter is simpby tcoleman - General
It starts good....but - 12 years ago
Just when I thought I had all of my settings right... The print started out just great. All except for the retract problem (as seen in BadPrint3). So I turned my back and let it run while I did some things for the wife (should have known better). When I checked later things had gone bad. With a small tug the print separated at the solid to fill layer letting one end rise squishing the printby tcoleman - General
Re: Electroplating plastic - 12 years ago
I do VM regularly in a bell jar with an E-Beam source (10 KV @ 8KW). It gets pumped down to a minimum of 5E-6 torr (mmHg). I'm involved in thin film solar panels(Cadmium Telluride) and I have coated everything from plexiglas to a frog mummy....yes dead things can be chromed..... our standard materials are aluminum and chrome. Have also done other things like quartz which wont stick to plastic becby tcoleman - General
Re: ABS glue? - 12 years ago
Oh no..Tetrahydrofuran (plus a few others harder to spell)....... way more kick than acetone or MEK. It's dissipated into the plastic faster than acetone so the glue joint cures faster. the primer is to clean AND pre-wet the plastic so the glue can go together before the glue loses its solvent and makes for a bad joint. The primer itself will glue a van tail light back together and lasted for anoby tcoleman - General
Re: PID problems - 12 years ago
Yes set as defaulted at .95. Ran autotune last night from a cold start. It worked quite well. My hats off to the boys who wrote that software. The temperature controllers and the E-beam evaporator controller I use at work don't self tune that well! Once tuned it held temperature like a champ. I still don't understand why it was so unresponsive the first time. The values it arrived at weren't veryby tcoleman - General
PID problems - 12 years ago
Hello, I'm kind of a nubee (at this) I was a Allen Bradley certified systems integrator and the only person for service for the Bandit series CNC's in North West Ohio for 13 years. These little machines seem to have the same kinds of problems as the big ones..or is that the other way arround...... Anyways I have a home designed system very little pre-made(kit parts) Made with IKO rail ways, ballsby tcoleman - General
