@o_lampe said in Closed loop firmware for CNC:

AFAIK, the current closed loop strategy in RRF is to add the missed steps to the axis involved.

I don't think that is correct. RRF sends a profile of the move via CAN, not step pulses. In closed loop mode, the 1HCL moves to the position at the speed dictated by the move profile. It doesn't really use steps; it uses the feedback from the encoder to position the motor. If the motor isn't keeping position, it increases current (up to a defined limit) until the motor has enough torque to achieve position. If it still can't keep position, it raises a driver error.

@3DOeste said in [3.6.0-rc.1] staggered movement duet2 ethernet:

and did the max flow rate test from 20 to 50mm3.

Was this using the flow tests in OrcaSlicer? I think I've heard that they are not RRF compatible, maybe they use adaptive pressure advance. Also check that the slicer isn't overriding the speed, jerk and acceleration settings in config.g.

What version PanelDue firmware are you using? Check by selecting the 'Setup' screen.

@3DOeste I was not sure ,from the other thread, if this is also fixed for you?

@Phaedrux Yeah I remember you mentioning that recently. Maybe the OP just needs to add those as well but if he didn't need them for 2.05 maybe there is a different behavior.

@3doeste unless you need more than 7 external drivers the easiest option is to use a Duet 2 Ethernet and take the 5 drivers from the expansion hears and the 2 from the Conn_LCD connector if you need them. You will be buying 5 internal drivers without using them but AFAIK the Duet is cheaper than a SAM4E dev board!

@timcurtis67 Hi, I was reading the help and apparently you can't dissable tool changes in powermill, it will allways write them with the first trajectory of a NC program. But I'm sure there must be a way to dissable them in the post, it's just my knowledge is limited, I simply edit a fanuc post and dissable eveithing I found that RRF won't interpret. You can write scripts, but I know nothing of programming.

I don't have the ability to post without a tool in powermill, but I don't know if you can in featurecam or in artcam.
