From memory, I think the numbers for fan outputs started at 20. So 20 should be Fan0, 21 should be Fan1 etc.by dc42 - Duet
Yes, that looks correct to me.by dc42 - Ormerod
You don't need it if you leave the 5V regulator on the Duet enabled.by dc42 - Ormerod
It's extremely rare for heater mosfets on Duets to fail. If your hot end is heating up more slowly than before, the most likely reasons are a failing power supply or a bad connection. In particular, check that the terminal block screws on the VIN and heater output terminal blocks on the Duet are tight. For more help I suggest you post at .by dc42 - Ormerod
Which problem: hot end not heating fast enough, or invalid M code?by dc42 - Ormerod
The text is wrong, if everything is aligned then the orientation parameter should be 20 not 21. Thanks for pointing this out. I will correct the entry in the GCodes wiki page. The entry at is already correct.by dc42 - General
What power supply are you using? Perhaps it can't supply enough current to drive more than one motor at a time.by dc42 - Firmware - Marlin
My Kossel XL has used the same Bondtech BMG extruder for around 4 years. I've never had a problem with it. The E3D Titan that it replaced used to jam.by dc42 - General
I see that your similar question at has been answered.by dc42 - Firmware - mainstream and related support
Take a look on stepperonline or another stepper motor catalog and look for motors with the same size (including length) as your motor. Pick the one with the closest resistance and use the rated current of that one as a guide to the maximum current you should use. If the resistance does not match exactly, the rated current varies approximately with the inverse square root of the resistance. Takingby dc42 - General
As @Dust says; except that extruders with very low steps/mm (e.g. 100 or lower) can benefit from x32 or x64 microstepping.by dc42 - Firmware - Marlin
@unfold I suggest you join the RepRapFirmware/TeamGloomy Discord channel. There you will find help with running RRF on a range of low costs controllers.by dc42 - Controllers
It looks to me that the kinematics is identical to a normal polar printer, in which case the standard builds of RepRapFirmware can drive it.by dc42 - General
What controller does your Folger use? The display you have purchased requires 5V signal levels, so if the controller only provides 3.3V signal levels then the signal levels will be out of tolerance and very sensitive to ringing caused by longer cables. If your controller board does provide 5V signal levels (e.g. it is one of the older generation of controllers using Atmega chips) then you may beby dc42 - General
Lighrburn and Duet/RepRapFirmware do work together. Configure Lightburn to generate G1 moves with the S parameter controlling laser power (this is also the configuration used by Smoothieware). If it's a laser engraver then in RRF 3.5 you can use up to 8 values in the S parameter of a single G1 command.by dc42 - General
Conditional GCode is not a standard part of GCode. There are several different versions of it. Which version you have (if any) depends on what firmware you are running. For example: RepRapFirmware: LinuxCNC:by dc42 - General
Yes, connect the negative outputs of the two PSUs together. Laptop PSUs normally use a two core mains cable (no ground wire) so it won't create a ground loop. The ground loops to avoid are the ones created when you connect the printer to another device such as a PC through a cable that has a ground connection e.g. a USB cable, and both devices have a connection between their PSU output and mainsby dc42 - General
You won't create a ground loop unless the grounds are already connected, for example if both PSUs have a connection between their negative output and mains ground. ATX and other PSUs intended for desktop PCa have such a connection built in but most other PSUs don't. You can use a multimeter to check for this.by dc42 - General
Yes you need to connect the grounds, however the SKR board almost certainly switches the negative side of its fan output. So connect the red fan wire to +12V from the 12V PSU and connect the black fan wire to the negative pin of the fan output of the control board.by dc42 - General
Thr 5V regulator on an Arduino is inadequate to power an LCD. It overheats, causing it to reduce the output voltage. Your options include: - Connect a couple of silicon rectifier diodes in series with the 12V input to the Arduino to reduce the input voltage. This transfers some of the heat dissipation from the regulator to the diodes. - Instead of powering the display backlight from 5V, power itby dc42 - General
It sounds to me that you are still running an older firmware version. Send M115 to check the firmware version.by dc42 - Reprappers
Stainless steel can be either magnetic or non magnetic depending on the alloy used. I use magnetic ones from Haydn Huntley.by dc42 - Fisher
I can't remember the construction of the Fisher, but could it be that a carriage that the rod tops are connected to isn't level?by dc42 - Fisher
Even with a Duet 0.6 you should be able to control the speed of the fans unless they are stuck permanently on.by dc42 - Fisher
PETG doesn't need a heated chamber. On my delta (not a Fisher) I use 80C bed temperature. I reduce the maximum speed of the print cooling fan to about 40%.by dc42 - Fisher
Yes, if you add an external resistor.by dc42 - For Sale
You can tell whether the sensor has started up in analog or digital mode by counting the number of LED flashes after power up. See the instructions at .by dc42 - For Sale
If the sensor doesn't detect a pullup resistor to +3.3V or +5V then it operates in pseudo-analog mode, outputting 4 different voltages depending on whether it is a long way from the bed, close to the bed but not quite triggered, close enough to be triggered, or overloaded with ambient light. If the board it is connected to treats the input as digital then it might see the "close to the bed but noby dc42 - For Sale
Hi @qunie, for faster response I suggest you start a thread at where the RepRapFirmware community and our support engineers will be please to help you. I took a quick look at your config files. For the BLTouch you used to have this M558 line: M558 P9 H5 F120 T6000 ; Set Z probe type to bltouch and the dive height + speeds You now have this one: M558 P1 C"zprobe.in" H5 F1by dc42 - General
