Hey, just a question to anyone that has used a remote drive extruder but is the shaft supposed to be choppy in its tubed/sleeve? The shaft itself is plenty rigid but when I turn it by hand it takes quite a bit more force to turn it 180 degrees than the following 180 degrees to complete a 360 degree rotation. Is this normal?by Power3DPrinting - Plastic Extruder Working Group

Marlin recently moved the settings: //#define LPC_SD_LCD // Marlin uses the SD drive attached to the LCD #define LPC_SD_ONBOARD // Marlin uses the SD drive on the control board from pins_RAMPS_RE_ARM.h to configuration_adv.h: /** * When using a bootloader that supports SD-Firmware-Flashing, * add a menu item to activate SD-FW-Update on the next reboot. * * Requireby Power3DPrinting - Firmware - Marlin
Quotenecris38 After a week of hard trying, configuration and other crying, I finally resolder all pins on Re-arm and Ramps plus Re-arm CPU with a hot-gun and then...perfect ! Thanks a lot for your help ! I ran into the same problem and I am confused why there are pictures of a full graphic display and not the discount smart controller from the title.

Hi, I built a large-ish CNC machine with a 2.2kw spindle and 7075 aluminum but and I am scared to use it because I cannot find reliable speed or feed values and I think the default values are too aggressive and will snap the tool. I have some aluminum 6061 plates I want to mill for a 3D printer heated bed support and other projects and I have some generic 2 flute and 4 flute high speed steel metrby Power3DPrinting - CNC Routers, Mills, and Hybrid RepRapping
My best work around is to tag an arduino pro mini and use the third fan pin to check the fan speed and then relay that as a filament runout error to the Z-max pin. If the pro mini arduino code works, I can copy and paste it into the config or main page and pray that it compiles and runs? Since I am in the realm of fantasy, if I can find the filament runout code then I can copy and edit it to a dby Power3DPrinting - General
A lot of bad things can happen when a fan stops working. Prusa has had an auto fan check for years now but I am struggling to find any information on how it is done with marlin and some three pin or something fans. Thoughts?by Power3DPrinting - General
I have no idea how to even open a rotary encoderby Power3DPrinting - General
This is a weird request, but for the rotary encoders on lcd screens, how do I make them quiet and get rid of the loud clicking? I am sure this doesn't bother most people, it is just a personal preference.by Power3DPrinting - General
Glad to hear about the skr boards are not too shabby? So long as they work, I'll keep in mind not to bother with customer support. RAMPS taught me how easy the boards were to repair or replace, ideally these 32bit boards are more reliable so I need not botherby Power3DPrinting - General
I am getting more and more interested in the sgen l vs the skr, it is a really good deal to get a board for almost free and stay in budget but having the blade fuses on the skr would make me cry tears of joy. Tough call.by Power3DPrinting - General
Thanks, that all means a lot, I grew up with RAMPS back when the Re-ARM was the most budget friendly non-hacky 32-bit board on the market so I am adjusting my perspective. I meant no disrespect to the skr, just wasn't sure about the differenceby Power3DPrinting - General
For 24V, Cartesian, TMC2208/2209, TFT35 V3.0, and general AUX 1 pinout for extras $11 RAMPS 1.6 and Arduino (I don't want to mod but I know how to for 24V and TMC) $21 RAMPS 1.6 and RE-ARM $21 RAMPS 1.6 plus and Arduino $29 RAMPS 1.6 plus and RE-ARM $1 MKS_SGEN_L 32-bit (the dealer cut me a deal if I buy some drivers they would throw one of these in with the buy, I like it, just never heard of tby Power3DPrinting - General

I am honestly changing my mind to a 235x235mm heated bed that can reach 110 degrees celcius but it is also a bit of a monster with current draw at 9.2A.A RAMPS 1.6 can handle it especially with active cooling. It is all the more reason to avoid the cheap rubber magnetic pads and go with N-35UH magnets. What is a good way to ask this, can the Ender 3 bed be modded with magnets underneath?by Power3DPrinting - General
Hi, If anyone has any experience with this, what do you think of kapton taping 30 N-35UH high temperature neodymium 20x6x2 magnets under a 220x220 PCB/aluminum heated bed? Does anyone know if there will be enough holding force through 3mm of pcb and aluminum to hold a spring steel sheet down? The Mk3S uses something similar but over a larger bed but also has a closer space between magnets and tby Power3DPrinting - General
Okay ha, well that is good to hear it is reliable, I got the wrong idea from what was said, my bad It is unfortunate there is no marlin support so I will sideline this project for now. Spool weighing has always been unreliable to the exact gram left in a spool or even within 50-80 grams, ideally the runout sensor gives a 20-30mm running low on gas alarm so the printer can take a pitstop for reby Power3DPrinting - General
Oh, okay Dust, I did not realize they stopped using the sensors, I get how the optical switch works but what is an interrupter? Good to know DC42, the magnetic sensor looks really cool but maybe out of my budget for all the printers I intend to upgrade, still probably worth testing out, do you think it has marlin support for RAMPS? MKSA I understand HAL effect sensors are great for driving motoby Power3DPrinting - General
I keep finding some of these modules here and there and for the price, it's not terrible value for what it offers. Any ideas why not every printer and its mother is getting sold and modded with one of these prusa sensors but almost every prusa mk3 has these sensors working?by Power3DPrinting - General
Cool to hear about passing production to duet, good company, I ordered a panel due for another printer, I did not realize you designed that too. Welp, I spoke too soon about the motors, I did several dozen test prints and found the motors create a significant amount of salmon skin effect on the perimeter walls and the Cetus MkII fixed extruder gear system needs to be overhauled because it cannotby Power3DPrinting - General
Also hi DC42, still selling those IR sensors? Really cool to still see you on the forums.by Power3DPrinting - General
Dang, I only just replaced all the electronics, so only way out is to replace all the electronics again or order new parts for an extruder? Axis motors work fine, they certainly get hot but none of them are handling filament and they are not skipping steps or melting their metal mounts, just obnoxiously loud.by Power3DPrinting - General
Hi, what do you mean look for new 3V motors? I checked some motors on other printers and you are right they all read under 3ohms. Unfortunately all the stepper motors on the Cetus read with 25-30 ohms. I don't really have any replacement motors for the extruder without ordering new hob gears and redesignng the extruder from scratch.by Power3DPrinting - General
Sorry all of them have labels that have been rubbed blank. One of them says "_____201" or "_____204" The most I know of them is that they are 32.3mm long and are 200 step motors and the two sets of coils each offer ~25.5-26 ohms of resistance. With 12V they will draw about 0.46A per loop so 0.92A or 1A motors by that logic?by Power3DPrinting - General
I have three Cetus MkII's with dead control boards converted to RAMPS, 12V 30A PSU, E3DV6, and other stuff. Their extruder A4988 stepper drivers are set to 1/3 current by their potentiometers before they skip and I have a 12V 0.1A 30mm fan cooling each extruder. I print at 40mm/s to not overwork the motor. Originally overheated in 0.5 hrs now it overheats in 1.5hrs. Progress I guess. Any ideas hby Power3DPrinting - General
