Re: 120v Silicone Bed Heater FTW! - 9 years ago
Double check that your power supply is set to the proper voltage. I accidentally had my power supply on 220v but it should have been set to 110v when it was set incorrectly. my previous 12v silicone heater didnt have enough juice to warm past 50 degrees and it was slow. flip the switch and its fine worth a check.by makerparts - General
PetG Warping - 9 years ago
Running into some issues of slightly warping with PETG filament. I use to have terrible warping with ABS and switching to PETG has been great,but i still run into it a bit here and there sometimes I add mouse ears to the corners of a print and this tends to solve it most of the time. My printer is not enclosed. I run my PEI bed at 60 degrees and my hotend at 235 any tips to help prevent petg fby makerparts - General

Never heard of alum mgn12 before. For my machine I run dual mgn12 stainless rails on x and y. It ads weight but for my setup it's much more convieientby makerparts - General
Re: Custom CoreXY - -Linear Rail Vibration - 9 years ago
The mechaduino is very similar to the ustepper. but i assume both of these cannot take advantage of very high microstepping rates as they ignore the built in driverby makerparts - General
Re: Custom CoreXY - -Linear Rail Vibration - 9 years ago
So who makes an integrated Nema 17 Servo ideally 24v that can just plug into a standard 4 pin motor connectorby makerparts - General
Re: Custom CoreXY - -Linear Rail Vibration - 9 years ago
These leadshine servos still appear to need a servo driver.. vs the ustepper/mechaduino which still just use standard stepper drivers. found on ramps/rumba etc. also finding a Nema 17 is ideal... Clearpath makes some nice Servos. but not in Nema 17 sizes i believe.by makerparts - General

So how can i hook one of these thermal fuses to a E3D v6by makerparts - General
Re: 120v Silicone Bed Heater FTW! - 9 years ago
Do these simply get wired in line with the silicone heater? How do they detect the temperture? Of the bed?by makerparts - General
Re: 120v Silicone Bed Heater FTW! - 9 years ago
Thats a good idea, can you suggest a model/part for the thermal fuse.by makerparts - General

Re: Ripped off USB connector from Rumba - 9 years ago
I tried a few times to get it soldered in properly. didnt end up working. but I noticed that just behind the Mini USB connector were 4 holes.. I happen to have some extra pins that i soldered into that spot.. then modified my usb cable to have a 4 pin dupont connect and now it works.. with a custom cable.. not ideal but it works!by makerparts - General

Ripped off USB connector from Rumba - 9 years ago
I accidentally ripped off the Mini USB connector on my rumba. I turned my printer while the usb cable was still plugged it and it flexed in a weird way and pop.. the connector came off. i tried to resolder it on the board and its on.. but it wont connect anymore to my PC. any advice ?by makerparts - General
Rail Resonance / Vibration - 9 years ago
I have a coreXY machine that is build with MGN12 Chinese Rails. I have been having issues with alot of sound / resonance during printing. I added some Nema 17 Dampeners and it really decreased substancially.. its not all gone but a big improvement. I suggest anyone with weird vibration/ resonance sound issues to install a pair on your XY steppersby makerparts - CoreXY Machines
Re: Custom CoreXY - -Linear Rail Vibration - 9 years ago
Cant wait until Grid leveling is on Duet Wifi, I have been using the Marlin UBL Branch with Auto Grid levelling and it works very well Roxy3D has done some great work. I am also increasing my printer to a 300x600 bed so grid levelling is going to get even more important.by makerparts - General

Re: Custom CoreXY - -Linear Rail Vibration - 9 years ago
BTW I am using 8825 Drivers on my rumba currently at 1/4 microstepping with a 400 rev Nema 17s running 14 tooth pulleys Using a 4 lines LCD display XXL reprapdiscount. current steps per mm is 57.14 I have also tried it with 1/8 Micro stepping with a XY step of 114.28 and it had similar performance.by makerparts - General
Re: Custom CoreXY - -Linear Rail Vibration - 9 years ago
Hmm well i just want it to run as quickly as possible while giving a good print quality. doesnt need to run at 100, 150, 200.. exactly. Hoping that 1/128 or 1/256 microstepping will reduce vibration, and that the reduced torque wont be that noticeable. any other thoughts on other ways to reduce rail resonance /vibration?by makerparts - General
Re: Custom CoreXY - -Linear Rail Vibration - 9 years ago
not sure how to measure the time it takes accurately to determine actual speed that its running at. I did place an order for a Duet Wifi With panelDue to help resolve this issue.by makerparts - General
Re: Custom CoreXY - -Linear Rail Vibration - 9 years ago
Thanks I will use the corexy forum next time. im running 1/8 Microstepping, to help speed things up. I have avoided the Duet as im waiting for Marlin to natively support a 32bit board. I was considering step sticks.. but im confused.. if im overloading the CPU with 1/16 microstepping.. then wouldnt going to something really high like 1/128 or 1/256 be crazy?by makerparts - General
Custom CoreXY - -Linear Rail Vibration - 9 years ago
I have build a custom made Corexy machine with Linear rails.. running Marlin UBL on a Rumba a few issues im having. I cant set travel speeds higher then 100mm/s it seems to bind or run into a cpu limit or something else. i thought it might be a missed step issue but i have carefully adjusted voltage on the Nema 17 400rev steppers to around 0.8Amps, and it warm but not too warm. getting someby makerparts - General

Stepper issue - 9 years ago
I switched out my 200 rev steppers for 400 rev steppers the wiring colour were totally different but i did my best and I believe i got it correct using DRV8825 Drivers set to 1/16 Micro I increased my steps per mm from 114 steps/mm to 228 step per mm but my machine is only moving half as much as i expected. since i increased from 200 to 400 i assume my steps would double to achieve the same accby makerparts - Reprappers
Re: GT2 Belt tensioner - 9 years ago

CoreXY speed settings - 9 years ago
Custom making a CoreXY machine.. My rumba cant really push this thing faster then 150mm/s not sure what would be a good value to start with for Acceleration and Jerk. Ive read many threads about this but it seems just trial and error.. is there a way to calculate a proper value?by makerparts - General
