Building S3 #508, I have a few questions

Post by buhmiller » Thu Sep 17, 2015 7:45 pm

Hi everyone, longtime lurker, 1st time poster. I am very excited about my purchase of a ShapeOko 3. I finally had the time to start the build. It has taken me a bit longer than normal as I didn't want to screw anything up and wanted to make sure I had everything done correctly. As with some, I have taken mine apart a few times. It is so much easier to put back together the 2nd and 3rd times! :)

Anyway, I have scoured the message board and haven't found any answers to my questions.

I am a complete noob to the whole CNC world, so I don't have any CNC experience to compare my S3 to.

So here they are:

1. The build document only goes up to page 22 on the most current .pdf that I was able to find and download, is there a more complete version?

2. When I plugged my S3 into my laptop, I was able to connect and control the gantry via Carbide Motion. When I jog the gantry in the fast mode, in any direction, the motion is not continual it stutters for just a fraction of a second, then goes again. Is that normal or do I need to do some tweaking?

3. When I did the "Hello World", it printed it out perfectly but in mirror image. I then swapped the y1 and the y2 cables and then it printed it out very scrunched. I found out that I have the wrong stepper motors in the wrong place, so I am going to fix that to see if that fixes the problem.

I am very excited to get to do some milling and know that I will be able to soon, I just want to get this as perfect as I can.

Thanks for any help!

Are there any S3 owners in Southern Alberta?

Welcome Todd, to find people in your area it can help to put your location in your profile so it shows up on the right side of your posts. I can't comment on #1 and #2, but "scrunched" prints are a common early issue. The dip switches for microstepping on the driver board ship set to 1/8, but grbl is programmed for 1/4. It's easiest to just set the switches to 1/4 to match. Later on, you might choose to calibrate your machine based on 1/8 and switch them back.

New version of the assembly instructions is here: http://bit.ly/1iAfiJQ --- still in process though.

I get the stuttering sometimes --- it seems to vary based on computer speed and other issues, Carbide3D is working on it. Having even belt tension for the Y-axis seems to help along that axis.

size is controlled by DIP switches (current default is 1/4 --- see http://docs.carbide3d.com/article/21-wh ... ller-board ) and step values in Grbl (defaults listed at: http://docs.carbide3d.com/article/38-sh ... l-settings ) ---toggle all your switches a few times and then set them as they should be (NEMA23, 1/4)

Thanks WillAdams and Hans. I changed the dip switches from ⅛ to ¼ and it prints out "Hello World" in the proper orientation albeit smaller. I am now going to try with the proper dip switch settings and see what that produces. I will post my results.

Success, I changed the dip switches back to ⅛ and it did the "Hello World" the correct way! I will post my pic/video in the hello world thread. Thanks Guys!
