Got it. Thanks for your help. Steve
Hi Peter, I'm sorry if I have misunderstood you. I think what you are saying is that Openbuild GCode generator is causing the pen to stay down...
I see. Is it the gcode generator app causing the problem or the control software. In other words, would I be able to draw open vector curves if I...
Here is an example. The straight lines should not be drawn with the pen.
I tried 'pen plotter no offset' and it connected the beginning and end of every curve in the drawing with a straight line (without lifting the pen)
Does anyone know how to draw an open vector, for example an arc, without a straight line connecting the end points of the curve? I am drawing the...
I noticed this error. [ATTACH]
When opening an svg drawing, does anyone know why I am getting "Generating, please wait... for ages?[ATTACH]
Thanks. I've actually just finished building it with 2040 v-slot. It is a smaller version which sits on my worktop at about 2m x 1m. I am...
Got it! I put both X switches in series and pluged into just X- on the shield. Now when I trigger either switch it causes GRBL alarm.
I think I found a clue. After I set $5 to Invert the limit pins I ttested the following: If I trigger one switch, say X- while a program is...
I've switched them to normally open and things are working. Your link does suggest that NC is safer though.
Yes, I tried that but it does't seem to work. I changed the following in the Openbuilds control 'Settings' panel First I set $21 Hard limits...
That's good. Thanks. I'll use normally closed. Do I have to change anything in the Openbuilds software, or on the Arduino CNC shield to tell it...
Hi again, I've finished building the OpenBuilds mechanical parts. I am trying to figure out the limit switches. I have the Arduino CNC Shield. Do...
Got it. OK. Thanks. I am very new to this hobby so a appreciate your help today. Thanks.
The stepper drivers can go up to 1/32. Is that useful for better resolution? Pololu DRV8825 Stepper Driver configuration: MODE0 MODE1...
One other thing. Bottom right of GCode app says that it can't connect to the Control app. Do I need to install drivers? I was able to export GCode...
Just tested it. Brilliant! Thanks. I may have some questions about calibrating. At the moment, the steppers are spinning like mad for even short...
Hi Peter, Thanks for the quick reply. This will work with my Arduino CNC shield? Servo control still in Z+ (D11)? Steve
