Just solved it, going to use dc motors and relays!by Tierod - General
Hello everyone, I’m attempting to design a device that has 4 small steppers, will have 2 end stops per motor, 1 at each end of the travel. I will use a current sensor to trigger one direction of travel and a lack of signal to move the other direction stopping at the end stops. Other than the current sensors I would like everything on one simple board(if possible). Any ideas? I have used an arduinby Tierod - General
Thanks for replying Dc42. That’s good news. I was hoping it would be part of the firmware on the duet. I’m in the middle of building my next delta so if it’s not a problem, do you have an approximate date for your next release? I never thought to check your forum, I will from now on. Thank you, Rodby Tierod - General
Im trying to find out if it’s possible to mirror the effector z height on a delta to add a separate z tower. Searched wilh as many key words as I can think of but no joy. I thought I read a post with this topic but not sure. I’ll be using a duet wifi with repetier. I need to match z heights exactly to try a type of filament drive system. Any help is appreciated. Thank you, Rodby Tierod - General
Dtwrv6 I’m currently building a new delta and plan to build a heated filament enclosure on top. What I don’t know is the ideal temperature to run it at. What temperature do you find the best? Thank you, Rodby Tierod - General
Mksa, ok,ok, was late, bit tired,lol. Foot pounds it is. Ok, back to timing belt thing. I was using that example because of the type of damper used. It’s internally spring loaded and oil dampened which also acts as a strong resistance to backward movement only. Moves quickly the other way. Unfortunately weight would be an issue because the best placement would be the carriage. But some form of seby Tierod - Mechanics
Shock absorber might work if done correctly. Take an automotive timing belt for example, many use a hydraulic tensioner with an internal spring rated for a specific belt tension. When vibrations try to push tensioner back it resists. It will move back but very slowly and with increased effort. If it could be made to apply the optimal pressure for any given belt, There would be no need for adjustmby Tierod - Mechanics
Had a mic 6 1/4 thick plate for about a year now. Best investment so far for my delta. I also have 750 watt 110 volt stick on and worried about it staying stuck so I sandwiched it between my mic6 plate, two layers of cork sheets, which just happen to come in 300x300 sizes from Micheals here in Canada(B.C). I also trimmed a spot in the cork to place a 145 degree(f) safety fuse. Under that I placedby Tierod - General
Thank you for the information I have a 20 tooth aluminum gt2 pulley so I’m going with Etfrench’s system It’s most likely a bit more forgiving than a printed gear. I have to say this, I’ve watch this forum about 4 years. I’ve been helped myself so many times in my hobby as have others. Thank you to all those who spend their time to help others! Cheers to all!!

thanks for the reply Etfrench so the higher the ratio the more accurate and better mech advantage. what ill do is see how small a tooth i can accurately print and go with whatever ratio that is. i should be able to print gears with at least 10:1 ratios with 125mm diam big gear. I'm going to try the nema 17 as I'm only drilling small holes in plastic and aluminum. I'm saving the link you gave mby Tierod - General
Hi everyone, I’m stuck, I’m trying to figure out the proper gear ratios for an indexing chuck using a nema 17 1.8 degree stepper I’m mounting the big gear (125mm printed) on the back of main shaft on a mini lathe. I’m okay designing and printing both gears but my issue is figuring out exact ratios to match the 200 steps. My goal is to turn the lathe chuck 360 degrees in minimum 1 degree incremeby Tierod - General
I would try reslicing your stl file, that worked for me. ( I believe it then uses your default to change gcode) Hope this helps. Rodby Tierod - Repetier
