Build some carbon fiber rods you be happy. I have not broken one rod since I made them. The first mod I made during my build. Also, if you have access to lowes or hobby lobby, home depot you can buy a sheet of acrylic and use one of your not broken rod and trace it and then just drill your holes and cut it out with a copling saw.by zaccom - Fisher
Build carbon fiber rods with the 6mm joints you be happy no more broken arms.by zaccom - Fisher
I found it didn't erase the old firmware and had some weird corrupt data. However, I had to switch to blue and green motor wires around and now it working.by zaccom - Fisher
I up dated my firmware with dc42 k version and now the extruder going backwards on all the commands. If i click extrude it goes reverse and if i click reverse it extrudes. Any thoughtsby zaccom - Fisher
Quoteph610 I am interested in the effector redesign and think I will given time swap over to a modified effector plate and maybe the arms as you all have described. Wondering whether zaccom has used the DC42 IR sensor yet on the effector and if it is working Ok on his effector plate modification? I am interested since I have a board already. Work in progressby zaccom - Fisher
Quotebgkdavis Ive been thinking about dc42s sensor board, but I think it will require a signifigant redesign of both the board and effector to work, I was wondering if it was practical to remove the ir comonents from the board and mount them directly on the effector for example. Yeah I got the board from him but need a slot in the effector to make it fit still work in progress if you find a goodby zaccom - Fisher
Quotebgkdavis That is just a direct copy of the originals all that has been done is the bottom and middle plates are merged together, it doesnt solve the problems I have with the original design and gets rid of the mdf plate which I actually want to keep. This version merges the top and middle plates and redesigns the ball mounts, this way I keep the mdf plate and solve the adjustability problemby zaccom - Fisher
There all ready one on Thingiverse and been working well.by zaccom - Fisher
Quotebgkdavis before the Armageddon I was down to 0.042 This was just the first calibration after the repair, now I've got the printer back working Ill try and get the calibration better. There is absolutely no backlash or slop in the ball-arm contacts and the whole kinematic assembly is a lot more rigid than before The only problem I see with these arms is getting them to size is tricky andby zaccom - Fisher
Did you ever fix the calibration to be lower than .007?by zaccom - Fisher
That would work well. I am going to get rid of the spring contact and use ir board to control calibrations. So no need for springs or bearings. However, the repositioning of the NOR switch would be a good idea if sticking with the basic design.by zaccom - Fisher
I like this concept I think I am going to test this out as well.by zaccom - Fisher

Front panels, Steel, 3 mm, one panel has ventilation and mount holes for 40x40x10 fan Side panel, Steelby zaccom - Fisher
Nice so on the print bed I also look at the baseplate since that would warp if heat bed was put on. I like how you insulated tips that you made. However, the main problem is the baseplate acrylic so both the bed plate and build plate i am going to replace.by zaccom - Fisher
Ok the bed thing driving me crazy so I am going to the aluminum even the base plate. For both sets is costing me right now at 200 bucks to make just one. However, not asking for money just how many are interested. The company will make major discounts after 5 or more is order. If you I can get a set set of 10 or more it will be 52.27 including shipping to my house in US dollars with all the holesby zaccom - Fisher
Ok so I sometime today to work on the magnetic effector plate that will make it even easier to mount the IR Board or just something to just basic printing. Still working progress have to put all plats together on this one and make 30 to 45 degree mounting place for countersunk magnets and then work on the railing system.

QuoteTheolodian What about using a carbon fibre panel to replace the acrylic and then putting whatever heated or not heated build surface on that? Melting point: for carbon fibre: 3500˚C but it will flex with what mixture you made the solid plate out of it. Here is a example but it is not cheap but can take serious heat you want something study still with polycarbonate or metal frame. I am goiby zaccom - Fisher
Quotepjr Looking good! My only concern is that you are potentially blocking the cable routing from the heater block to the cable tie point on the effector. The positioning of the heater block itself is important per the fisher instructions to avoid overheating the air vent nozzles and the proposed position of the IR board. I was looking at a possible mounting on the outside of the effector on thby zaccom - Fisher
So far it is just a make up on places the board is going to be set in grove where ever the board goes up so there still 1mm or .5 at the above the nozzle. Still have to look at what external parts that could get in the way. I finish a complete build with arms and screws in place with all the fastness and see what I can. Whisk I could but the board I little angled but I think the ir deflect and noby zaccom - Fisher
To replacement part 2 plates fully assembly. Not for Mini IRby zaccom - Fisher
Ok I have a mockup possible spot for the mini IR, but not done. However, I make the effector button plate that has both bottom plate fused and top plate is by itself. dc42 will this work with your board? I will finish it with screws and stuff once I know this going to work. Replacement effector or spareparts. Do not make in pla unless it high heat rated like carbon fiber will take heat.

Ok here is a basic test fit on AutoCAD for basic effector. The two Bottom plates are one piece and top piece is the lid. Everything else fits and aligns up. I working on the Mini IR at this moment. But here is basic effector.by zaccom - Fisher
Ok so I have the dxf file for the lower effector plate that i will be working on incorporating a high heat carbon fiber so that the dc42 Mini Ir will fit close and mount to the nozzle as possible. I might have to fix the fan ducts to help hold the board but will not mess with the airflow. Also this will give other option with connector rods. Once done with my prototype and I get the board I sendby zaccom - Fisher
I don't have my calibration tools on hand what is the thickness of the effector assembly on the fisher.by zaccom - Fisher
I working on a design so it will fit on a new effector design. Congrats on the E3D deal. I might have to get more IR boards off of you later down the road. I like the Duet setup and much easier to deal with than individual stepper boards and then another controller board it get messy.by zaccom - Fisher
Quotedc42 Thanks fo sharing. 1. It sounds like you have your slicer configured to generate absolute extrusion coordinates. Use relative extruder coordinates instead. If that's too difficult, add a G91 command at the start of sys/pause.g and sys/resume.g. 2. Edit the sys/homedelta.g file on the SD card and remove the G1 movement command at the end. 3. The Fisher extrudsr is direct drive so theby zaccom - Fisher
Nice work. Have you though of designing a one piece Effector plate to replace the all the plates?by zaccom - Fisher
Quotedc42 Quotezaccom I forgot to ask will I need to make my own wiring harness or does this come with one? I supply a connector, but you need to make your own wiring harness. For an extra charge I could make one for you, but I would need to know what controller electronics you use, and how long the wires need to be to reach your electronics. I am using the Duet Board, I will make the wiring haby zaccom - For Sale
