Hi, I’m not new to 3d printing, but firmware has me stumped. I built a RS version about a year ago and life took over and it was set aside. Now I have time to get back to it and need to load the firmware into arduino. If I use the config h file that is on github I get an error that “NUM_AXIS was not declared in this scope”. I dont have the smart controller installed yet until after I get the machine running, but that should not matter for everything else. Can anyone tell me why I am getting this error? I am using arduino 1.6.7 if that makes a difference.
Could you send the complete error log. NUM_AXIS is used at a lot of places in the firmware and it’s a bit hard to pin point the issue.
You might be interested in getting Marlin-RC version instead of Mjrice build for your Wilson RS as it doesn’t have the added code that is needed for Wilson 2 (rack and pinion Z probe, etc…)
Here’s the “Classic” Marlin-RC firmware : https://github.com/MarlinFirmware/Marlin/tree/RC
You should check Mjrice Wilson TS original build video for the configuration setup.
Hope this help.
Thanks for the reply, I downloaded the most recent Marlin and spent a few hours researching and tweaking config h to get things working right. I did watch the video and was surprised to see how close my numbers were with the video. It was a pain, but I guess I can do it if I have to.
All is working perfect now.
Has anyone ever designed a print cooler to work with this machine?
https://github.com/mjrice/wilson/blob/master/stl/extruder/FAN-DUCT.stl should work fine if you have the direct drive extruder.
Thanks andreq, I dont know how I missed that. The printer is working great, but I work a lot in abs and petg and the only way for me to get bridges right is with cooling.
Do you have good success with cooling with ABS. I’ve transformed my cooling fan into a hotend cooling duct as I didn’t like the result of the fan blowing on the extruded plastic. Was I doing something wrong?
I have had great success with abs since I started using cooling. I have 2 ecksbot machines, I bought the first one as a kit and built the second from scratch. The cooling fan I use on those machines is directed close to the hot end, but blowing across the print surface http://www.thingiverse.com/thing:91128 . This fan doesn’t blow on the hot end, but across the part below it and I have excellent luck with bridges up to about 1-1/2 inches across with little to no sagging. I hope I can get the same results with this machine. The ecksbot has a .45 hot end and I built this one with a .35 hot end. Time will tell, but I think where the air hits makes a huge difference.
