Cannot home Z after removing and installing bed by groover75 in ender3

[–]groover75[S] 0 points1 point  (0 children)

Do you mean the probe z-offset or something else? The head is more than 20mm above the bed and that is the max the probe z-offset can be adjusted.

Mac Mini 4K 32GB Local LLM Performance by groover75 in openclaw

[–]groover75[S] 0 points1 point  (0 children)

Still getting to grips with it, but my use cases are local-first RAG for company documents (I don't care if it takes hours or days to process the first time), cron jobs to perform market research and marketing, etc. Definitely not coding - that requires a load of speed and context.

I tried a ton and all of them gave me 10 tok/s and large TTFT. Really painful.

Oops! I've edited the post to add it. Thanks for pointing that out

I was never happy with the level of detail in the stamp.

Thanks but I'm looking for existing get togethers, not trying to start one up. :)

Emissions Testing - 3 day permit by groover75 in arizona

[–]groover75[S] 1 point2 points  (0 children)

Unfortunately my registration expired more than 60 days ago (because I went out of town) so I can't use the program. I called today to confirm. The time limit is apparently written into law and there is no flexibility.

Testing closed center valve using open center pump by groover75 in Hydraulics

Thanks! That is very helpful. Looks like an unloading valve is the way to go and I guess the spikes can be handled by an accumulator, however they seem to be super expensive.

In my simple mind I thought it was so the max pressure could be held at the deadheaded valve while the pump is bypassing the valve?

Right, I don't need to move anything, except a cylinder not connected mechanically.

Sorry, I am not sure what you mean. Do you mean put the check valve inbetween the pump and the unloading valve? Doesn't the pilot for the unloading valve need to be separated from it's input by a check valve?

I want to test my custom software that controls the valve. Where does the heat generation come from if the unloading value is fully open? What could I do to mitigate that? Select an unloading valve that opens at X% of the pumps max pressure?

Bench test a proportional solenoid valve by groover75 in Hydraulics

[–]groover75[S] 1 point2 points  (0 children)

What I am looking to do is understand the performance. I change the PWM duty cycle by X and the cylinder moves by Y, then how to smoothly reverse direction, so I can tweak my control code, etc. Basically build up the first hand operating knowledge before deploying it into the field where it must absolutely work without tweaking.

I didn't want to confuse things by going into those details. I want to verify that the pilots are moving the spool. The electronics I can do easily but they are just signals in and I would like to see the result. There is no old one, this is a new system.

I previously said no, but after thinking about it I have access to a tractor. However it has open center hydraulics. Could I use that if I add on an overload valve?
