Current 3D Printer Failed (BAD)

Mostly Printed 3D Printer - MP3DP Advice
#1

I know that this isn’t exactly an MP3DP topic, but I also know you guys have experience across the board so I was hoping for some advice. I have an Anet A8 (heavily customized) and now an Eryone Thinker SE that I purchased a couple of months ago from a neighbor. Well, the Thinker just tried to light my house on fire (see picture).

I emailed Eryone and they told me my board is bad and I should buy a new one for $50 from amazon. They were even kind enough to send me a link.

I obviously do NOT trust this company or thier product anymore and I do not want to support them by buying a replacement board. I was considering buying a RAMPS 1.4 to get the machine running again, but was wondering if you guys had any better ideas? It would be nice if I didnt have to re-wire the entire machine but it might come down to that. Here is the replacement board for reference: https://www.amazon.com/ERYONE-2560-Main-Board-Thinker/dp/B083R91NLN

I just want something that will run smoothly, not break the bank and if possible, maybe even use some of the same JST connectors that the machine currently has.

After a small amount of research, it seems the SKR 1.4 Turbo can support my current drivers (TMC2208) and should work with the built in display of the printer, is only $38 and runs Marlin which I am familiar with. I would still have to rewire everything though. Might have to just accept that…

I see at least a few of you agree on the SKR board. I see that Ryan has an SKR 1.2 Pro for sale, but I am not sure the difference between that and the SKR 1.4 Turbo? Is it just that it has a spot for an extra stepper driver and the power area has a cover? Also, do you guys have any recommendations for reliable places to buy these boards? I have typically just gone to the cheapest thing on Amazon, but I would prefer to do business directly with the supplier of a quality product and cut out Amazon entirely…

And one last thing (for now, give me another 5 minutes to think of another!), any idea what the name is of connectors the SKR boards use? They look similar to the display connectors on most printers. Thinking I might just make some adapter harnesses to my JST style plugs so that I don’t have to chop mine up.

The biggest difference for us CNCers is the pro has a configuration in MarlinBuilder releases. The turbo doesn’t. There is a skr (not pro or turbo) 1.3 config, but it is not as well tested as the pro.

For a printer, the pro has big mosfets and wire connectors, a spot for an esp-01 for wifi control, and 6 actual endstop connectors.

Ryan gets a big box of the skrs from bigtreetech. You can also buy them from banggood or ali express. If you live in Australia, it is probably better for everyone to buy it from bg and send Ryan a beer over paypal.

I think the motor connectors are JST-HX? I can’t remember the last two lettters, but they are 2.5mm pitch.

Does that just mean that Marlin just doesn’t support SKR1.4 Turbo so there is no official release? So I will have to download something that someone has already set up or work through it on my own?

Wish I would have realized that before I got impatient and bought the turbo. I guess I will probably still want to upgrade the mosfets for the heated bed and nozzle element then. Maybe that would have helped prevent the Eryone board from catching fire…

I think you were close, I just ordered up these JST-XH connectors from ebay. Hopefully they are the same as what are on the SKR. The thing that is throwing me off on the SKR is that it has black receptacles and I usually see those JST receptacles in white.

Thanks again for the help!

Marlin supports the turbo just fine. The MarlinBuilder repo is for V1 machines.

The turbo should be fine. I think if you had a 300mmx300mm 12V heated bed, then you might need bigger mosfets. But to be safe, look up the current requirements and make sure you have some headroom. Those burns might be from the connectors more than the mosfets.

Yeah, you’re going to need one. I just built a machine with the SKR 1.4 Turbo and a 310x310 12v bed. If you connect it directly to the board, it reboots as soon as the bed heater turns on. The one I have draws about 17amps by itself. I believe the SKR board is only rated for 15 amps max for everything.

I checked the shop and didn’t see any so here’s the one I bought.

It actually is a 300mmx300mm bed but its 24V. Still going to upgrade the mosfets. It’s worth the extra 10 bucks.

Looks like my machine is 24V, and the power supply maxes out at 14.6A so I might be ok, but I think the dedicated mosfet for the heated bed will give me peace of mind.

I had used a SKR 1.4 Turbo with TMC2209 for my build and worked through the Marlin config to get it up and running. My files may be of use in comparing to other versions (like stock Marlin, for example) for changes: https://github.com/Kuhlio/MP3DP_Firmware
