Any idea when 1HCL will be available to US resellers?

T3P3Tony

@alex-cr we have orders in from at least Filastruder (need to check with the other ones). I hope we will start shipping reseller orders to them next week.

Much appreciated!

@t3p3tony Anything for Germany/Europe? I am currently testing 1XD with SERVO42C but that makes little sense if 1HCL is available soon.

Apologies if this was addressed before but I was wondering why the choice of using the 5160 and it's built-in encoder input was not used?

T3P3Tony

@cloudseeds we have dispatched some to Compass-DHM and Dold Mechatronic , I hope both of them will list them soon.

@madmattco the EXP1HCL uses the TMC2160A because it supports the direct coil current control that we need for closed loop node. The TMC2160A does not support an encoder. In any case, reading the encoder using the built-in encoder support in the MCU is faster than reading from the stepper driver over SPI.

I have a question can I use mini with 1HCL board ?

T3P3Tony

@martin7404 yes you can use it with any of the Duet 3 Mainboards (6HC, 6XD and Mini 5+)

Hi @t3p3tony,
Are there any 1HCL units on the way to UK resellers? I've checked E3D and Oozenest and nothing is showing there at the moment.

Many thanks

Any one using EXP1HCL boards with firmware 3.4.0RC1, please upgrade the EXP1HCL firmware to 3.4.0RC1+2 available at https://www.dropbox.com/sh/2dt7sbqpx6l74np/AADn4-lpcil1iqnWKkiVri3Ia?dl=0.

Has there been any progress on simultaneous tuning of two motors driven by individual 1HCL? I’m looking to control a dual motor Y axis gantry with auto squaring.
Thanks
