Slanwar - PB will be on its way. Thank you. I managed to find some time to get some other stuff completed as you can see below, on the KosselFlex I have also included a couple of other images I thought worth sharing. This post should address a couple of questions I have had recently about retraction performance on the Flex3Drive, aswell as the request for Kossel Mini info. Here is the hotend faby Mutley3D - General
I will PM you to resolve this urgently. Did you email the old mutley3d.com or new flex3drive.com domain? Quotehobbymods Quotehobbymods Hi Mutley, I made an inquiry through your website some time back, regarding getting a couple of your Printbite sheets cut to 240x240mm and posted to Australia. No reply at this stage....can it be done? Here I am again....I sent another email a few days back juby Mutley3D - General
Given you have an extruder product and claim hundreds of hours testing, along with many materials tested, it might be advisable to have a strong selection of good prints to boost your kickstarter potential otherwise people might question the veracity of your product. I know of only 3 possibly 4 prints you have put in the public domain that were apparently printed with the Zesty. Just in case youby Mutley3D - General

regarding the self levelling. The Flex3Drive for Kossel Mini comes with fittings that have attachment points for the DC42 IR self levelling probe so this will all fit as standard. with the Flex3Drive. Also the PrintBite comes with its own adhesive backing attached - just peel and stick.by Mutley3D - General

QuoteMechaBits They look almost injection molded, good luck. Thanks. They are all printed using a Flex3Drive. On PrintBite, Black ABS, 0.12 layer heights, no brim, no post processing. Straight from print to assembly.by Mutley3D - General
It has been a long road, and a lot of hard work. I hope you find it of interest and of use, please do share it about. Got a plan, sticking to it, and now a page turns. Below is just a selection of what is available. www.flex3drive.com is the new home where you can find out more. There is also a pre-release program running for the Chimera/Cyclops dual drive Flex3Drive, which includes a cby Mutley3D - General
@Mechabits I am very respectful of what the Zesty guys did in approaching me, and really cant speak ill of them in this respect. Whilst I cant/wont divulge details there is not any issue with having to wait for royalty style payments, A modest deal was agreed and completed. I prefer the quiet life. Possibly there is an angle coming that because my designs are not or were not released under theby Mutley3D - General
apologies to wider community if this is tl/dr but I have had to make sure I was crystal clear in this post for legal reasons. @Brian, I have and continue to honour the agreement. I am an honourable individual, as anyone that knows me will vouch (including yourselves i hope). Personal experience has shown me people can try to abuse that nature. I have experienced how such people can act in a verby Mutley3D - General
Brian, you have deliberately taken out of context the clause in question that was inserted for your assurance. Yes I wrote the agreement based on the lengthy discussions we had. It was my error in judgement to act in good faith and keep the cost of our agreement as low as possible for your benefit by not getting a lawyer to review it. I perhaps made an error in placing my trust in you, but hopefuby Mutley3D - General
In response to Brians post - I have asked him to clearly state in no uncertain terms that he wont deliberately misinterpret or misrepresent to lawyers the purpose of that clause - edited for legal resaons -by Mutley3D - General
Chris33 (and anyone else) - Please stop posting about Flex3Drive and nimble in the same sentence - There is an agreement in place and these guys are accusing me of prompting you and others to post (which I am not doing). They have threatened legal action and continue to hold the threat of legal action against me. Please delete your post, so I can edit mine away. You are doing me harm. - edited fby Mutley3D - General
reprappertech filament is cheap and cheerful. As Enlightx mentions you get what you pay for with filament and reprappertech is one of the better budget filaments, but is still budget range. It is not worth flaming a supplier just because you got a bad roll. Who knows, it might have even been your machine having a glitch - everybody's machine is "perfect". The guys at 3dfilaprint do a great jobby Mutley3D - General
@etfrench That sounds like a win. And within pretty respectable engineering tolerances. Well done for perservering. Key is getting temps and bottom layer height "just right". I fancy your chances without the brim and pads nextby Mutley3D - General
These guys are spamming multiple forums all across the place, not just our beloved reprap forum. It appears as though they have still managed to spam even with the new account reistration process. Is there any way that if a detected chinese text character (or several of them) was present on western speaking forum pages, they could automatically get rejected when the submit button was pressed?

When using an ali plate of any substantial thickness consider if there may be a temp differential between the top surface and your thermistor location. An IR temp gun (if you have one) might help by providing a top surface temp indication for comparison to the given thermistor based reading. Or a multimeter with a thermocouple attachment.

Nylon trimmer line is going to be unpredicatble material as we dont know what else is in it, but lets treat is as nylon for now. I have heard of others printing such material no issues onto printbite so its anyone guess with this stuff. Nylon is a high temp material, so I would suggest going higher with your nozzle temp, 260 - 270, if only for your bottom layer. Bed sounds hot enough. If this fby Mutley3D - General
QuoteconG Hi, Seems to be something like PrintBite and BuildTake. Can you give us your opinion about it to compare easily ? Just to avoid confusion - This is nothing like PrintBite, which in turn is nothing like Buildtak.by Mutley3D - Crowdfunding Projects Announcements
Hi Graywolf - if you are not able to reach temps then PrintBite wont work as effectively. Applying a weak ABS/Acetone will increase adhesion but I would advise sorting the heatbed circuit. A standard Mk2a heatbed correctly wired with a with a half decent RAMPs/Arduino and LED PSU should easily be able to hit 120c and above. If it cant do this it might be a sign of an issue or potential fire riskby Mutley3D - General
Aha ok I'm with you now. I thought you had motors at the bottom, and were talking about compression of the coupler aswell as twist. The pitch of your Z screw (8m lead?) will increase the load on your couplers. as will your anti backlash nuts of they are over tightened, but then you already know this. You might want to look at Oldham / Silicone / Elastomer / Spider couplings that are used in CNCby Mutley3D - General
Helical couplers work well for the task they are designed for. This task does not include supporting a vertical load. When using helical couplers, ensure that the lead screw is resting upon the top of the motor shaft, and allow the helical coupler to take up non concentric and off vertical movement only. It also helps to use an effective Z axis isolator between the X axis and Z axis lead nut, pby Mutley3D - General
I may be wrong here but as I recall, the pulse signal interrupt timer for the stepper motors runs at x4 - if a motor speed signal exceeds the system limits it will drop the interrupts to x2. This may explain the speed differential being described above. Regarding the firmware limits, the 4th parameter in the line below determines your E axis speed. If the value you set here goes beyond the systeby Mutley3D - General
PrintBite can be stuck to anything that is flat. I will always recommend the safe approach of using mirror or tempered glass because it is known to be flat and will remain flat when heated.. Ali tooling plate that is cast and milled flat can also be used. Ali sheet however is not cast and can warp during heat stress therefore I wont recommend it. Of course people are welcome to deploy in the mby Mutley3D - General
QuoteGrillSgt @Mutley: Are there any ideas how to remove the printbite surface from the heating bed? I don't want to damage the printbite. I've bought a new MK3 alloy printbed and want to use it on them. It is not too difficult to remove. Get a scraper under one edge/corner, you should then be able to peel it off. Just bear in mind it will take some force to peel off however the PrintBite sheetby Mutley3D - General

I doubt you will draw more than 15 amps @ 24v on the heatbed size you mention above. Maybe Traumflug can chime in on this.by Mutley3D - General
icefire Easiest quickest cheapest least hassle most reliable approach in my view would be to acquire a 24v PSU for the heatbed, and run it through a sevenswitch Connect the 24v PSU and heatbed through the sevenswitch, and use the 12v heatbed output from the RAMPs to drive the sevenswitch.
