Question from a very new guy here, I have recently built the R7 machine and it’s the greatest machine ever. So along with my new addiction there are questions. I’ve got it running and have tried a few practice jobs (chillipeppr logo, the circle square calibration pattern.) but i have recently come across an issue. the SPDIR light keeps flashing when attempting a job, the spindle moved 10mm then just stops and, the SPDIR light just blinks. What is it, and how do i get rid of it? second how do it tell chillipeppr the size of my spoilerboard so i can utilize all the space avaliable? Also any beginner tutorials would be greatly appreciated.

Almost forgot. I’m using a Tiny G board, and win 10

Hi there Chyle,

Not sure about the blinking light but when it comes to setting up your work area, you should check out the below guidelines:

You will need to make sure that all of your limit switches are exactly the same. I didn’t realize it at the time but I was using two extremely similar but different switches and the machine ended bumping into the end, ignoring my switches. I have found the g28.2x0y0 setting to be the most useful. This homes your machine. Before that, set up your ‘work’ x0y0 using the instructions in the link also make sure your limit/ homing switches are working.

Thanks Kevin! Will do.

That is an interesting one.
Are you using the spindle dir pin?

No I didn’t know if that was possible to hook that up. If it is, I would like to control the spindle speed with the software instead of manually.

What did you guys use to mount your limit switches, and also where did you mount them. I have a few Ideas and wanted to know what you guys did.

Hi Chyle, I 3D printed mounts that clip on to the aluminum rails. They work great but take up space which could otherwise be used for cutting. I will redesign them later.

Can they be made of wood or plastic because i don’t have a 3d printer yet.

@Smoov215 I don’t use them but there are a set mounted on our R4. Same set up would apply to the R7.
You can operate without them, but…
If you get the limit switch plates, Tee-nuts, and M5 bolts, you can install them in the slots on X and Y and install the Z on the bottom of the C-beam end plate.

There are a couple of threaded holes on the back of the plate. The Z has to be angled slightly to get the proper height but works.

Spindle control- yes it seems this is possible. We have the parts to test it but keep sliding on the date to complete the upgrade. @Eclsnowman mentions this on one of the R7 post here somewhere. There is a small board that ups the voltage on on the PWM signal. It does not appear to be a direct plug and play though. Appears some have to add s transistor and a few resistors. We will hopefully get to this hack soon. Once we do we will post it here and in the new forum.

Ok thanks
