SimianSteam please e-mail me directly as I cannot use your username here to find out what ticket you have. I do not answer anything through the ticketing system as that is not my job, we have an employee that handles all that (Paula).

@EddyP Please e-mail me directly at chelseat@qu-bd.com so I can look it up as I don't know what order you have as I don't know based on your username who you are.

@Regpye as I am not aware of the exact situation that caused the nozzles to be that way or why the replacements weren't sent to you, although occasionally things can be missed. Please e-mail me directly and I will get them out to you personally. Please include your order number.by Chelsea - QU-BD - General
Also, not that it makes much difference but the value of the entirety of the returned merchandise, in unaffected condition, at retail is $385.00 not the $716.02 that was mentioned. Additionally I am showing that between the ticketing system, and direct e-mail that there are 17 messages replying to you over the period from Feb 3rd to now.

While I don't think it is necessarily the best place to talk about this stuff I thought I would clear the air. Jkerr purchased several products which he told us he wasn't able to make work correctly. As per our return policy: "All unaffected items may be returned within 15 calender days from the date of delivery for a full refund less shipping and handling costs. After 15 calender days all saby Chelsea - QU-BD - General
We've had an 'introductory' printer done since March, we have just been testing and tweaking this whole time, that will retail for $199 (kit and only as a kit). We may have ours shipped before Makibox does...by Chelsea - QU-BD - General

Yes you can wire them in parallel together although you will need a very large power supply AND a relay to drive them as it will overload all of the standard electronics. We have a 300x300 bed (out of stock) and a 600x600 bed (also out of stock) and can make custom sizes although there is a pretty hefty lead time at the moment. You will need an energy density of about 1.5 watts per square inch tby Chelsea - QU-BD - General
We actually use them on our MBE extruders and the Y axis and Z axis of our Revolution printers which move around quite quickly so they do allow quite rapid movement over long periods of time. Chelsea - QU-BDby Chelsea - QU-BD - Tantillus
Hey guys, just thought I would chime in for a second. If the motor is getting hot then the stepper driver is turned up too high and/or does not have adequate cooling, its not a problem with the motor. Additionally the low speeds that a Tantillus can run at should not be taxing the motor at all. Also, thermal shutdown would be caused by the stepper driver overheating not the motor. We supply aby Chelsea - QU-BD - Tantillus
When we were designing our printers we asked the same question. Generally speaking linear shafting has a diameter tolerance, straightness tolerance and finish level (in RMS) and has been case hardened to 'file hard'. Drill rod generally does not have anything but a diameter tolerance and is generally a crapshoot as to exactly how straight and smooth it is. With that being said a lot of the driby Chelsea - QU-BD - General
They are fine to move at 1Meter per second which is double the capability you were looking for. We have tested the 4988 and they simply don't work for our setup at high speed. Chelsea - QU-BDby Chelsea - QU-BD - General
Our stepper drivers (out of stock at the moment, hopefully they will be in shortly) from Panucatt have no problem to over 1M/s so you would have plenty of headroom to gear them down. Roy @ may have some in stock. Chelsea - QU-BDby Chelsea - QU-BD - General
We have 12x12 20A@12v and 11.75x11.75 10A@24v silicone rubber heaters in stock. 12x12 11.75x11.75 You will need electronics that can handle the current or a separate relay to control the heaters as well as a basalt, glass or other substrate to mount the silicone rubber heaters to.

It looks to me like you are probably losing steps in 'X' and 'Y' because the acceleration parameters (and possible max feedrate depending on what speed you are printing at) are probably not optimal. Try changing the X and Y parameter to 1000 for acceleration and just giving that a try to see if that solves your problem before bumping the values up. Chelsea - QU-BDby Chelsea - QU-BD - General
Perhaps what I said wasn't totally clear, in no way am I criticizing our MBE extruder, I have been pleasently suprised how few problems exist relative to the user base. Also take note that the Revolution, Revolution XL and RPM all use a brand new cold end that is not based on any other designs (the X-Truder!). We will be releasing our new design in a very open way.

Thank you for taking the time to make that post, you bring up a lot of good questions that I would be happy to answer. There have been people that have had problems with our extruders but it all has to be taken in context. As we know 3D printing in general can be 'fiddly' and ALL extruders require proper calibration to behave properly, there will always a failure rate above 0.

Please send me to where you saw the 350mm build size, that it an error and needs to be corrected. There might be a little confusion since we have three different printers being sold simultaneously. The RPM does have a 332mm long axis? Revolution (small belt driven) Revolution XL (large belt driven) R.P.M. (Revolution Prototyping Mill) (HUGE and ball screw driven) Chelsea - QU-BDby Chelsea - QU-BD - General
Maybe I'm misreading but are you looking for a reason that it is moving quickly or a reason that we posted the video? We were happy to acheive that speed and acceleration while still carrying a full extruder with motor around. I have seen other printers move that quickly (OrdBot / Ultimaker) but not while carrying an extruder and in the Ultimakers case, not without a huge amount of vibration.by Chelsea - QU-BD - General
Make sure that the stepper is wired with the correct pairs red/blue green/black . You should be able to look inside through the UHMW block on the opposite side of where the filament adjustment screw is to make sure the motor is turning. Chelsea - QU-BDby Chelsea - QU-BD - General
In regards to the 'X-Truder'... -No the cold end is completely different and totally not compatible with the current MBE extruder as the motor size is different. -No, there is no need due to the way the filament is fed, it cannot slip, period. We will be carrying ProtoParadigm filament in our store that we will be recommending, although other manufacturers high quality filament will work just fiby Chelsea - QU-BD - General
The advantage of a Bowden cable designed extruder is the low mass which allows fast and controlled acceleration and deceleration. The disadvantage is stringing and oozing. If you could have a direct or geared extruder that was as light as a Bowden cable setup or close to it...that's what we did. At less than 6oz of total weight which includes the motor we can get the same acceleration figuresby Chelsea - QU-BD - General
Sorry I wasn't a bit more clear, the extruder is mounted in the video, its just an all new design that is unlike anything currently on the market. It is geared, weighs less than 6oz including the motor, its all metal and it can keep up The X-Axis is 232mm in length.

This is a quick video of our machine aluminum Revolution XL printer doing some speed tests. The production version will have cable management in our Nanolinks cable chain and have bead blasted anodized parts instead of just raw machined parts as in the video.

We actually are out of stock right now but we normally carry a 12x12 silicone rubber heater that draws 20@12v. We are expecting a lot more in shortly. Chelsea - QU-BDby Chelsea - QU-BD - General
Typically the linear bearings use EXTREMELY hard ball bearings internally...like file hard. When they are coupled with a shaft that is not as hard or not nearly as hard, like stainless steel they can and do wear into the shaft which increases the play that is introduced between the shaft and bearing which will affect print quality negatively. The weight of the object being supported plays a bigby Chelsea - QU-BD - General

Discounting our printers because we are biased... I have seen all of these printers in person except for the Mendel 90 and new Lulzbot printer (although I have seen the older one). Out of the printers on the list the Ultimaker has surprisingly good consistent prints with Lulzbot coming in a close second only because its more expensive.
