Hi Theo, I have E3D hot ends on several printers. They wrote an interesting piece on printing with carbon based filament and just how severely it wears your print nozzle. Carbon wears so badly and mishapes the nozzle that they sell a stainless steel one just for carbon, Don't take my word for it, just have a look on their website and see what you think. Cheers!

Hi BgkDavis, Ooh, I like that! If that's an I-beam section, It should be pretty strong anyway, even without the carbon reinforcement. I'm not sure from the drawing, it could be 2 separate pieces with a carbon rod sandwich. I'm electrical rather than mechanically biased - we think differently :-) My inspiration is simply that at the moment, I am short of arms to get the printer working - evenby BAD455 - Fisher
Hi all, This is a quick picture of my proposed strengthening design for an emergency printed replacement arm for the fisher. There is a 2mm wide, 2mm deep slot in the middle ready to accept a length of 2mm diameter carbon rod - super glued in place. I have used the idea before when reinforcing model aeroplane wings made of polystyrene and it has given good results. How it will perform on the pby BAD455 - Fisher
Quotedroftarts I have answered Ian separately by email: We would really like to understand how they have broken. We haven't had any breakages in 6 weeks of testing! Please could you consider, and give me some feedback, on the following: 1. Please send me a picture showing how they have broken. Send any other pictures that may also be appropriate. Pictures to follow in daylight. 2. I understaby BAD455 - Fisher
Hi again Droftarts, I'm a bit busy at the minute, but I thought I would just post to let you know that I have read your post. I will post pictures of the ones that I broke along with some pictures of the ones I have printed from thingiverse - by Ortwin. The printed ones have some flex in them even though I printed with 100% infill. I was thinking of doing a re-work of them with a 2mm channelby BAD455 - Fisher
Hi bgkdavis, I think that it's your model I downloaded from thingiverse last night - thanks for that :-) How are you guys going about upgrading to carbon? Using rc car rod ends and gluing into carbon rod? If so, could you pass on the dimensions please? I might have a trip to the model shop! Thanks for the help lads - much appreciated:-) Ianby BAD455 - Fisher
Thanks for that Droftarts. That's just what I was looking for :-) I did notice that you have been updating the documentation today - I was almost folowing along with you. As I refreshed the pages, you were adding files. Unfortunately, I have overtightened the effector rods and 4 have snapped at the ball mount. I mistakenly imagined that you tightened the pins up until the rods held up in the aby BAD455 - Fisher
Hi all, My first post on the forum :--) I received my Fisher 1 yesterday and started to assemble it. This is my 4th build and it's going very nicely with the easy to follow instructions. There have been changes from the beta version as you all know - I discovered them when putting together the motor assembly and could not find the required size bolts (as per the beta build log). I figured out wby BAD455 - Fisher
Hi again, Thanks for the reply. I have no excuse, it was just laziness on my part - Photos! genius. I have attached 2 - they are supposed to be the centre lower base of Rich Hornes 3DR delta printer. The drift just seems to happen at random stages. Sometimes with 2 layers, other times right at the end of the print. Other than this, the quality has been quite good - it's my first build. The hby BAD455 - Printing
Hi all, I am in the process of gathering all of the parts to make a 3DR and I read Rich's blog about using Traxxas parts for the carriage arms. My local model shop (Penn Models, West Midlands) has a great selection to choose from and the guys in there just let me have a look at everything and measure up for what might be suitable. I think that the following parts and numbers might be useful foby BAD455 - Delta Machines
Thanks for the replies guys, Sorry I have been a while geting back to this - time has not been on my side these last few days... I think both points are valid, but, I'm looking for another reason. My limits are wires normally closed. They break when the hotend is home, therefore if the wires had broken, it would see home position from anywhere along the x-axis. If my print starts 50mm over (forby BAD455 - Printing
Hi all, First post on here - I've been soldiering on by myself till now, but this one has got me stumped. I have made a Prusa i3 single plate (aluminium) and have been getting ok results until the last week or so. I keep getting this random drifting of the print on the X-axis (the one attached to the z-axis in case I have got it wrong). A print can be going fine for and hour and then just starby BAD455 - Printing
