@TheGarp Check the driver in Device Manager, recently a Windows update has been replacing the wch driver with another that doesn't work with the CH340g UART. You can either roll-back the driver or manually reinstall back to the correct one.
Don't bypass the net framework bit. Check you port number by plugging in the board to your PC then looking at Device manager for the com port number. Once you enter this in to the s/w it should give a connected message.
Next step is to load the ch340 driver. This is the rather hidden dow arrow in the top right corner. Once that is done it all sort of springs in to life.
As an alternative, T2Laser includes everything you need in a single install. The CH340 driver can be loaded from the Help menu, just click the link and you can use the firmware already installed on the Nano for testing or install my 1.1e DEFAULT for optimized performance.
@totenpf Are you talking about my custom firmware?
They are described in more detail in the manual, those marked with a * are compatible with the Eleks boards but each has it's own specific purpose:
· *1.1e (default) includes support for homing on D9 and dynamic laser power
· *0.9g J-Tech. Supports most systems, uses 7.8KHz PWM
· *0.9i EleksMana
· 0.9j Woodpecker
· 1.1e Non-PWM
· *1.1e Axis Swap
· 1.1f LaserAxe. Uses custom pin outs for some of their machines (others can use the default firmware)
· *1.1f High Frequency PWM
· *1.1f XY Home Sw.
· *1.1f CNC Z-XY
@ibarra23 Well I'm glad you told me it was a dog, because I never would have guessed that
I would suggest you start with some simple shapes, circles are a good choice as you'll see immediately if they are connecting (start to end) or not, and then you can repeat the same job again and see if it matches or is shifting.
These tests will tell you if it's a backlash (belt) issue, motors losing steps (current or friction) issue or something else.
I don't know what parameters you can change in EleksCAM but if you slow the machine down (feed rate) does it improve? Steppers have higher torque at slower speeds so if it's current or friction it may look correct or at least closer if this is the case.
