I need also to adapt the top to all three driving systems ( fishing line, racks&pinions and GT2) so the model will be maybe changed, but basically, it would be a real idea steeling You found just something i trieby regpye - Smart_Rap

Quoteduranza New smartrap probe/hot-end plate Hey all, I have a little present for you guys. Take a look a this little mod. I will be testing it tomorrow and when all is good I will post some STLs for whoever wants to upgrade. This will help out with eliminating the torque of the normal arm, as this only allows up/down movement. I like it, very clever. Can you send or direct me to the STL fileby regpye - Smart_Rap
Re: Stabilizing X Axis on 0.4.7 and Earlier Designs - 11 years ago
QuoteBackEMF You can also put some paper, or soft plastic between the LM8UU and the top clamp. the 0.47 has 3mm holes on the sides there so that you can clamp it down by screwing M3 's in. LOL @ Reg, it's cheaper to drill a hole in a coin then actually go to the hardware store to buy a washer. Not in my case. I have over 60,000 washers in stock already.

Re: Stabilizing X Axis on 0.4.7 and Earlier Designs - 11 years ago
Quotex86Daddy I built my SmartRap using mostly a set of parts based on the 0.4.6 version. I may upgrade to newer parts over time. The main thing that bothered me was the amount of bending upward the X axis does during Z-homing, exacerbated by the fact that I'm using a servoless probe method. I figured out a quick 2-cent solution, literally, and figured I'd share. I haven't tested it much yet,by regpye - Smart_Rap

Re: Which hotend for a smartrap? - 11 years ago
Quotenapalmvictory You can buy another hot end, but chances are you'll have the same problems no matter what product you buy. Bowden setups have lousy performance with retraction. No hot end is going to fix that; it's just physics. If you want better performance on retraction, go with a direct drive system. I think 90% of the time, the best hot end is the one you already have.

I have been lucky so far and not needed it, but I did read somewhere that a guy had this problem with a Mach3 setup and had to use shielded cables.

Quotezackary Many thanks Sogeking.... I have a camping gas stove that I may be able to use instead of a blow torch ... Not as good I,m sure but loads cheaper for me!! Hopefully will get some time this week to try it out. Thanks again!! Camper stove will work well - safer too for the nozzle.

Re: Greg's SmartRap Build - 11 years ago
QuoteSogeking Hi Greg, I find that the best solution for fixing a blocked nozzle is to use a blowtorch. This seems to be the most common fix for this problem and I've seen Reg posting this before. Poking the nozzle with a thin sharp object might damage it. Unscrew the nozzle from the hotend (when cold), remove the PTFE liner, hold the nozzle with a pair of plyers and use the blowtorch for a fewby regpye - Smart_Rap

Re: Rack and Pinion drive - 11 years ago
QuoteCellJeffe Someone in another forum mentioned "sinusoidal" herringbone gears. That has me intrigued. Presumably, the helical gear mesh path develops sinusoidal error as the meshing teeth progress along the slant. A sinusoidal mesh pattern might compensate -- double it to a herringbone pattern to cancel the axial thrust. Unfortunately, the only thing I can find on sinusoidal herringbone gearsby regpye - Smart_Rap
