Tricklaser Ball Cup Arm Length Question

Post by MrSteve920 » Tue Oct 31, 2017 9:43 am

I have a question about the arm length on the D300 plus upgrade. It was my understanding that the tricklaser ball cup arms used for the upgrade are 375mm measured from ball center to ball center. However, I noticed that the config file for the 1.19.2 upgrade for the plus on the github is coded for a 379mm diagonal arm length. Where does the additional 4mm come from?

379mm was the arm length needed for dimensional print accuracy on our reference D300VS+. It will be a good value to start with.

Quickly... for dimensional accuracy you may need to adjust your diagonal_rod value. Increase the value if actual print size too big and decrease if too small. Use the following formula to correct the diagonal_rod value:

Code: Select all

new_diagonal_rod = diagonal_rod * (measured_print_size/required_print_size)  
Adjust the value in the config.g file:

Code: Select all

After further testing it turns out 375.0 for my arms marked 375.0 gives me the right size prints.
