Re: Calculating Travel per Revolution

There is no way to simply tell it to take a specific number of steps. If you told the axis to move 1" with the travel per revolution set to .197 and it moved exactly 1", then .197 sounds like the correct number. By the way,0.197 inches equals 5.0038 mm and ball screws with 5mm pitch are very common....

Re: Calculating Travel per Revolution

In most instances, users will get the step angle or steps per revolution from the stepper motor data sheet. if given the number of steps per revolution (or steps per 360 degrees), you can calculate the step angle by dividing 360 by the number of steps per revolution. Be aware that the step angle ref...

Re: Network access to the internal flash drive

I'm glad CAMotics is working for you. There will be a new version coming out soon that provides the ability to download g-code directly from CAMotics to the Buildbotics Controller. We are very interested in your touch screen connection. We have been thinking about choosing a touch screen monitor to ...

Re: Network access to the internal flash drive

I installed 'samba' on my Buildbotics Controller and here's what I found. I was able to publish the folder where the g-code files (/var/lib/bbctrl/upload) are kept by using the instructions posted at the following link: https://raspberrypihq.com/how-to-share-a-folder-with-a-windows-computer-from-a-r...

Re: L1/L2 controll through G-Code

M7 turns on L1,
M8 turns on L2,
M9 turns off both L1 and L2

Hope this helps,
Doug

Re: Network access to the internal flash drive

I think this is possible. We have to be careful not to overload the RPI by adding 'non-essential' features to it. Having said that, there is a program called "samba" that allows sharing folders with other computers on the network. We are definitely interested in "tightening" the workflow. Being able...

Re: Buttons to run files or macros

I see your point and Joe and I will discuss this at our upcoming meeting. In the mean time, you might consider creating a special configuration for making PCB's. For example, after you get the machine configured properly for PCB's (e.g. probing is removed from the tool change procedure, and probably...

Re: Buttons to run files or macros

Thanks for your suggestion. Have you looked at the 'tool-change' field on the Settings page? You can enter a g-code script in that field that will be executed every time a tool change is encountered. I have my machine set up to prompt me to attach the probe, then it seeks toward the probe until it i...

Great. I'll consider this issue closed unless you tell me that it still doesn't work.
