That is what I would think is meant by dual axis but I’m surprised it does not mention anywhere what the dual axis was going to drive for the 2nd axis. ie it should have stated if X_AXIS then the X and Y axis motors will drive as X, if Y_AXIS then the Y and Z axis will drive as Y.
BTW, I would not be messing with github to look at the configuration file. Didn’t you clone the repository to your local system… That is where I’d be looking through the config file for hints in the comments.
Guess I must have missed something. Wasn’t expecting anyone to do anything for me other than confirm or comment on what I thought was an acceptable solution for someone with no soldering skills, who has tried repeatedly to master it, and still cannot.
Understood, not everyone finds the same skills easy. Sorry this conversation went a little off the rails.
It doesn’t have to include soldering. Usually you don’t want to solder cables to pin header connectors anyway; crimping is better. Additionally, if you are using external drivers, many of them have screw connectors and you can daisy-chain them. If you are using screw connectors, you want to protect the wires with “bootlace ferrules” to protect the delicate wire strands from being cut by the screws. I bought this:
It’s also possible to drive two motors with one stepper driver, though there are tradeoffs. Do you know about the possibility and the tradeoffs?
Hi Michael and thanks for the reply. Large paws and arthritis disqualify me from delicate work, such is life.
I wondered regarding the ‘stacking’ of driver modules, i.e. the ones that slot into a conventional control board, whether or not there was enough pin sticking up to attach anything to as my first thought was to use an ‘intermediate strip’ (can’t remember the exact definition, header pin connector?) between them.
I’m looking at using integral drivers as regards the standalone variety to use on say a cnc with two Y axis motors, or a cnc laser with a heavy carriage on the same axis requiring a fair chunk of current that one driver will not provide.
Now if my understanding of the situation is incorrect then someone please correct me, that’s why I’m asking the questions.
No, you can’t just stack them; at least, as I understand your question. I don’t know what board you are using though.
With arthritis causing trouble soldering, unlikely that the delicate work of cutting and bodging traces would work. Slaving axes in software is clearly better for you!
Are you aware of the new work being done on grblHAL? I haven’t checked whether they have implemented slaving axes there, but it’s where the future of grbl seems to be happening right now, as far as I can tell.
32-bit boards are cheap these days. I’d suggest taking another look, because they really open up so many more options. This is especially true when it comes to solving problems in software instead of hardware. It’s not just grblHAL; most of the interesting firmware development today is happening on 32-bit controllers, most of which are based on ARM.
Hi Michael, yes I’ve been considering the 32 bit boards although since Brexit/Covid we in the UK are having shortages and prices seem to be increasing exponentially!
Definitely on the list of things to buy though!
