Duet and Panel Due. I have 2 printers and 1 cnc mill using this set up. I'm a coding/firmware retard. If I can make all this work, and work well that's saying a lot. Strong support system as wellby Bill Clark - General
I have the NSS's. I believe the MKS is a copy of his board. There is a Google support group for NSS and the developer is active.Go have a look I think the Nano Smart stepper you are looking at on Aliexpress is a clone too.by Bill Clark - General
QuoteWesBrooks Thanks for the notes on TG. I've got a few ideas on the back burner which will need a heated chamber. Sure. I was going off of memory this morning and the Tg for the 9085 was incorrect. It is 185 also so chamber and Tg are the same for 9085. The Ultem 1010 was the one that has the chamber set about 5 degrees lower than its Tgby Bill Clark - General
The Stratasys 400mc prints Ultem 9085 at 185c chamber temp. 5 degrees lower than the Tg. PEEK or PEKK would be a lower (chamber) temp option. A chamber temp slightly lower than the Tg seems to be typical. There is no heated bed in the 400mc. It is the same temp as the chamber. Intamsys is about your only reasonably priced option that can effectively print the high performance plastics other thanby Bill Clark - General
I bought a Intamasys Funmat HT for our machine shop at work to make fixtures and tool organizers. It's basically a fully enclosed Ultimaker with 90c chamber cabability and a 160c bed. Direct drive extruder, ball screw Z and 450c hotend (includes a lower temp hotend). It really shines with ABS and PC. Does all the lower temp plastics well. Trinamic drivers and over all built well.

QuoteWesBrooks That is toasty! Which material needs that heat - or is it more with the heat the part is better rather than 'need'? Heard that PC wasn't really happy until the bed temperature exceeded 135C. I haven't done PC on it yet but some 9085 Ultem and PEKK at 90 chamber and 150 bed. It does those materials ok but not as good as the Stratasys machines we have. The higher temp materials ideaby Bill Clark - General
I have a Intamsys Funmat at work that I have run at 90c (max) chamber temp and it suprisingly does very well. Although I haven't torn into it yet the kinemetics appear to be the same as the Ultimaker. All of the belts, steppers, direct drive extrusion system and bits are inside the chamber and get very hot but still work as intended. Unfortunately I don't know what materials they are using but Iby Bill Clark - General
This may be far fetched but have you verified the extruder motor has stopped completely on non print moves? Perhaps there is a tinny bit of creep. Also do you have linear advance or some type of pressure compensation active?by Bill Clark - General
This probably isn't going to help is effortsby Bill Clark - General
I have a cheap Kill A Watt P3 P4400 meter bought off of amazon on one of my printers and it bounces around between 90-150 watts while printing. if I set the bed and hotend (50w cartridge) to a high temp (so both are 100% duty cycle) while printing it shoots up to around 600 watts. This particular printer runs the X and Y motors on a separate power supply set at 38v. Z, E, hotend, control board,by Bill Clark - General
Like TDD mentioned above the limiting factor tends to be the rate that you can melt and deposit plastic.Try extruding in air at the rate that would be required for your target print speed first and work that out.by Bill Clark - General
Several months ago I put a 200×200, 500w silicone heater on one of mine. Over kill for most but ambient to 160c in a little over 2 minutes really makes me hate the time I used to wait for the bed to come up to temp. 70c in less than a minute, I would never go back to a weaker setupby Bill Clark - General
QuoteLoboCNC I'm a little reluctant to dive into this snit-fest, but despite cwaa's abrasiveness, he does have a good point - a lot of products (not just open source ones) have really poor documentation. There's the assumption that certain things (network configuration, how & where to make connections, what have you) any halfway competent person should be able to figure out, but that's onlyby Bill Clark - General
Quotecwaa Duet is about money! dc42 lives and breaths this stuff and has an obvious passion for it. I doubt money is his primary motivator. I had a similar issue to yours, was able to get past it fairly quickly and consider myself a computer retard.by Bill Clark - General
QuoteRoberts_Clif If 3D Printers have been around sense. The first 3D printer ever created in 1983. And heat chambers were then common knowledge before this patent, any heat chamber patent in itself violates the patent laws. Agreed but for us folks without a team of lawyers its nice to know that there's less chance (even it was already a remote chance) of them sending you a cease and disist afterby Bill Clark - General
QuoteBluemonkey Is it 1 year or 2 years ? I think it's from the filing date rather than the priority date but the priority date makes more sense. Not 100% sure but I did read on one site the 20 years starts from the priority dateby Bill Clark - General
Unless I'm missing something it looks like the Stratasys patent for high temperature modeling apparatus is going to expire in almost exactly 1 year from nowby Bill Clark - General
QuoteTrakyan Correct me if I'm wrong, but his travel moves should be slower since he's moving a bigger, heavier gantry and carriage with the same nema17s used with smaller, lighter setups. Plus acceleration should probably be set lower because of the longer belt paths being more susceptible to stretch. That aside, I think arduinos are plenty powerful for the linear kinematics of a CoreXY at any sby Bill Clark - General
I second the Duet. You can run the 2130's Up to 44v with marlin, ramps, arduino. Just power the motor voltage pins with the higher voltage and the ramps with 12. Easy peasy. I am using the 2100's this way on one of my machines. I will say I could not get the 2130's to work right with marlin but believe it was not related to the way I was powering them. IMOP You will not see the full potential oby Bill Clark - General
Certainly been life changing for many of us. Thank you for you contributions Mr Bowerby Bill Clark - General
If you have the protectors under the stepsticks the power sequence doesn't matter. With or without the protectors it wouldn't hurt to follow the recommended power up/down.I run my 2100's on 42v and the motors love it. You will find you can dial the current back too. Typically the motors we use on our printers can be run up to around 60v.by Bill Clark - General
I was planning to just sew my own cellular type from nomex. I have access to a 900mc to study. They use cellular like window blinds. I need 220c capable.by Bill Clark - General
Fortunately I do have access to a 900MC to study and they do use a cellular type barrier but don't know the material. I plan to run chamber temps over 200c as they do to print Ultem 1010by Bill Clark - General
Quote691175002 I'm currently designing a personal printer that is pretty much a straight ripoff of their patent. The original mechanism is actually fairly clever, although I suspect that it would have been discovered by hobbyists had it not been developed by Stratasys. Have you given any thought to what type of material or a source for the accordion thermal barrier separating the motioby Bill Clark - General
So the appropriate way to determine what would be required would be to measure ripple with an oscilloscope?by Bill Clark - General
I recently upgraded one of my 12v printers with TMC2100 drivers for the X and Y. These drivers like at least 36v in my combination and I may want to set them as high as 42v (driver max V = 45v). Currently I am powering just the drivers with a Drok 0-48v adjustable power supply set at 36v with a single 63v, 100uf capacitor.. Instead of the Drok I would like to add something like this and power itby Bill Clark - General
my steps/mm was off after I installed TMC2130's. seems the Marlin FW update did not override eeprom. once I noticed that I was over that hurdle. Had other issues, through in the towel and installed 2100's. Now its printing away and I have to keep checking if its actually still moving. What voltage are you running to the drivers? My TMC's were crap in stealthchop on 12v. powered the Vm/grd. with 3by Bill Clark - General
I bought a Robo back in 2014 that was manufactured in China and it had 5/16 rods (.3125") on it. Dont remember the bearing fit but I believe they where appropriately sized. I chucked those for new 8mm (.315") rods and matching bearings. This might be what you are experiencing if, by chance the parts came from the same source. I have also found that getting rods and bearings from different sourcesby Bill Clark - General
