Any thoughts on this board for a MPCNC? what drivers would you recommend?September 8, 2019 at 10:45 am #112566
32 bit is evolving rapidly still. Unless you are comfortable with Marlin edits maybe give it some more time.September 8, 2019 at 12:20 pm #112581
already running marlin 2 on my 3d printer and I do like the greater memory availablity for future upgradesSeptember 8, 2019 at 5:19 pm #112619
Well than, I hope it is a good choice cuz I just bought one!September 9, 2019 at 4:48 am #112685
what drivers did you get?September 9, 2019 at 5:57 am #112700
2208 but the 2209 is what seems to be the ideal when they start to become more available.September 12, 2019 at 2:44 pm #113846
I’ve got one on order as well, with the 2209 drivers. Looks like it will be next month before they can ship it.September 13, 2019 at 4:21 pm #114062
Does anyone running a SKR pro mind sharing their firmware with me please?September 13, 2019 at 4:27 pm #114065
I have not plugged mine in yet. If you need firmware you also need to state what drivers and how they are installed (uart, spi, non of the above). It is a pretty configurable board you will probably need to get in and change things to suit your needs at some point.September 13, 2019 at 4:31 pm #114066
I’m using TMC5160 on X and Y using SPI. I’m using a TMC2208 on the Z using UART. I think I have a handle on changing the configuration for the type of stepper. Just not sure about the pin configuration.

Interesting. I wonder if you can use both at the same time. I hope someone that knows weighs in.September 13, 2019 at 4:38 pm #114069
I hope so 😂. The 5160s came in a 4 pack and I didn’t want to wait for a 5th.September 13, 2019 at 9:25 pm #114083
here you go gents – config for SKR Pro v1.1 – with TMC 5160 V1.2 drivers.
Make sure to change the platformio.h to platformio.ini for correctivity;)
best of luck!
*the TMC drivers are set to 1200ma — i’ve not run the machine beyond 45 minutes at a time, the motors get warm but not hot for me, but overheating motors can be a disaster for your project as well as soften PLA motor mounts – make sure to pay attention to this!!

well just ordered mine with the 2209 drivers and the tft display from aliexpress.
now to see what I can find for a printed case…September 15, 2019 at 10:02 am #114202
I just watched an Alex Kenis video. These 2209 drivers might be a bit of a nightmare for a while. Looks like two of the larger suppliers are making them with different pin outs. So I am not sure how this is going to work in the firmware yet but it looks like he is going to have a review/overview of them soon.September 15, 2019 at 10:12 am #114203
yeah I saw that too he is an AMAZING source of info much of it goes over my head but I learn every time I watch his videos.
hopefully if I stick with Bigtrees drivers on Bigtrees board I’ll be OK. And they do seem to be pushing their firmware into Marlin so fingers crossedSeptember 15, 2019 at 12:00 pm #114210
Hey guys jumping in here with some updates on my experiences.
Did some trochoidal milling of brass yesterday evening after losing a cylinder head dowel for my KX. I have previously attempted to go without the dowel (used to locate the head gasket properly) with non-optimal results. In effort to have a good ride today (it was successful), I had to have a dowel pin!
12mm OD, 10mm ID – 14mm length.
So I cut a pocket in some 3/4 inch plywood, hammered in a 1.75″ square bit of brass stock (C360) at 14mm thickness and proceeded to cut the dowel pin. The operation was about 30-35 minutes run time with some intense activity on all steppers. The process went off smoothly, though I’ll be making a low profile vice for the machine asap – wood pocket workholding may be too much of a compromise.
At 1200ma the steppers didn’t obviously seem to lose any steps, but I can tell you that they were hot! Almost but not quite too hot to touch.
11.6mm OD (worst performance, maybe there were steps lost:/), 9.96mm ID (was blow away), and length was dialed in on a manual mill.
I used a bit of .0015″ shim stock to make up the difference on the OD. Beat the hell out of the moto and its holding up.September 15, 2019 at 6:49 pm #114244
I finally got everything working with mixed stepper drivers. Thanks for your help. Now I have to figure out how to control my spindle and laser.September 16, 2019 at 9:02 am #114343
Keep us posed on the spindle and laser man!
I am looking hard at a 800w 65mm watercooled unit for those sweet sweet lower RPMs.
Also lasers are just cool in general.
let us know how you go.September 17, 2019 at 2:50 pm #114488
also picked up the wifi module for this….now waiting on the shipment of the board and driversSeptember 23, 2019 at 11:43 pm #115236
I did the SKR 1.3, drv8825 drivers, works great, and I got an education too!
If you know how, or learn how to compile firmware, you will be fine, if not, like Ryan Said, be ready for an education!October 10, 2019 at 6:44 am #117401
I have not plugged mine in yet. If you need firmware you also need to state what drivers and how they are installed (uart, spi, non of the above). It is a pretty configurable board you will probably need to get in and change things to suit your needs at some point.
Ryan have you plugged yours in yet? Mine has finally shipped (2209 drivers…)
any thoughts on sensorless homing for dual end stops?October 11, 2019 at 8:24 am #117523
I just got confirmation this morning that my 2209’s shipped.

great I think mine has as well…aliexpress tracking is broke …
are you going to ERRF?October 11, 2019 at 12:22 pm #117555
No ERRF for me, maybe MRRF.October 12, 2019 at 12:16 pm #117661
@ryan lol Tom mentioned you in his live steam saying he wished you were there

Rough stream, about when does he mention it, middle, end?October 13, 2019 at 11:13 am #117741
some one on the stream asks if you are there. He says No and that he wishes you were because he would like to talk to you face to faceOctober 13, 2019 at 12:01 pm #117745

I really like the SKR 1.3 i got and am keen to upgrade to the pro for the LR2 and use the 1.3 for my printer.
Them TMC2130s are great for sensorless homing and running ‘dual endstop’ squaring etc. Nice having all 5 motors on their own drivers and their own end stops without all the yuck wiring you need haha. Big fan… big big fan!
Keen to see how you guys get on with the pro and the 2209s! Do you run fans for cooling? Do you need cooling for the 5160’s?
I put 2 fans onto my 1.3 and 2130s with some ducts over the stepper heatsinks with some vents where they meet in the middle, and configured marlin to run the fans whenever the steppers are enabled (and 2 min afterwards)October 17, 2019 at 7:20 am #118182
question – could you power a raspberry pi from the skr-ori board? looking at pin outs I see 5V pins….not sure of the amps…
