QuoteMCcarman MKSA. - Yes power and gnd are only to power electronics. Such as NON separately powered USB hubs, Inline data converters or even micro computers. Power and gnd are the 2 outside pins. Note that phone CHARGER cables some times ONLY have +V and earth. Data cables don't have the +V. OK, Then I can tell you that not to connect the GND/0V IS STUPID and a way to potentially blow the USBby MKSA - Prusa i3 and variants
QuoteMCcarman Quote??? And that took 3 edits!. Time for a beer I think. Or maybe you already had one. Stay well folks. When you wrote " I can't remember which pins but there is only 2 that it needs." do you really mean you connect ONLY these two signals wire, not V+ and 0, GND ?by MKSA - Prusa i3 and variants

The unnecessary solutions people use like 2 and 3 motor bed leveling, mesh bed compensation, and quirky bed sensors like bltouch or piezo ones. Don't take my statements as implying that low-tech is a bad thing. Low tech means simpler, probably more reliable, and most certainly cheaper. But hey, likeby MKSA - CoreXY Machines

I have chinese made ball bearings where the races were SOFT steel ! I am pretty sure that in addition to loose tolerances, these junk linear bearings are not properly heat treated and grounded ! I have seen these guys on youtube who replace the undersized balls with better one. Just that they degrease everything, assemble then show how well the parts move freely ! These are JERKS who have NO cluby MKSA - General
Most probably these linear rails were made out of recycled Lychees cans. Therefore this is totally normal. The ones running smoothly are made with recycled Soviet era nuclear submarines. They are better just a bit radioactive. So you are lucky. Note they can be recycled as Lychees cans. How much for your Duet ?by MKSA - General

QuotePower3DPrinting ... MKSA I understand HAL effect sensors are great for driving motors, never throught to use one as a jam detector but makes sense one could be used in the same way as the duet's magnetic sensor. While not being able to detect filament runout reliably is unfortunate and I'm not sure why, ..... ??? It IS reliable, the point is that it takes a few cm to detect the jam ! Theby MKSA - General
Quotedc42 We tried a laser sensor too, but there are some filaments that it just doesn't work with. We found it more reliable to use the filament to turn a shaft and measure the motion magnetically, so we made this . As with the laser monitor, the firmware correlates measured extrusion with commanded extrusion so it doesn't only detect complete jams. I integrated a radially magnetized torus (9X4by MKSA - General

Quotejay_s @sdavi I definitely saw a difference in response times between RRF2 and RRF3 but I was using two different MKS boards. I thought the slow down I saw was of a result of the board I used for RRF2 having a borked driver (amongst other things). For me, on RRF2, it took about 5 minutes to load DWC. After that, everything was fine. I have a spare MKS board and will do a comparison test beby MKSA - Firmware - experimental, borrowed, and future
