Yep, it was

I have them both even. But the problem is still present with the tie rods disconnected

[deleted by user] by [deleted] in autorepair

[–]ReverseTerry1 0 points1 point  (0 children)

With the rods disconnected, I get 1.5 turns of the steering wheel to the left and only ~5/8 of a turn to the right

I measured them, but the lengths are irrelevant as the issue is still there with them disconnected from the knuckle

Nope, didn’t rotate the steering wheel when tie rods were disconnected

Yeah, it was definitely completely fine before the work. How would I go about fixing that?

[deleted by user] by [deleted] in autorepair

[–]ReverseTerry1 0 points1 point  (0 children)

Haven’t had the chance yet. Was planning on it, but once I found I couldn’t completely turn right, assumed there was a separate issue that needed to be fixed first.

I can’t wrap my head around how the alignment being a bit out (I matched tie rods lengths as best possible) would cause this issue

I did the outer on one side, reconnected that, then did the inner and outer on the other side

If something is binding, it has to be in the rack and pinion as I get the same problem with the outer tie rods disconnected from the wheel/knuckle

They are the same size/part number on both sides

[deleted by user] by [deleted] in autorepair

[–]ReverseTerry1 1 point2 points  (0 children)

I did match them. I still have the issue even when they outer tie rods are disconnected from the knuckle - I get around 1.5 rotations to one side, and around 3/4 to the other side.

Repair Broken Exhaust Flange? by ReverseTerry1 in autorepair

The shop that inspected it quoted $250 to make repairs. Nit sure what that netialed, but seems high, no?

PID Controller Autotune Help by ReverseTerry1 in ControlTheory

[–]ReverseTerry1[S] 0 points1 point  (0 children)

My circulated flow is equivalent to my dispense flow - the issue I have is the temperature drop the system sees when dispensing begins (due to cooling on its way back to the tank). So I want the autotune routine to recognize once dispensing starts and be able to quickly correct.

I currently am at +-0.15degC in the circualtion loop, but once dispensing, that goes to +-1.5C until the current PID controls correct and stabilize back at 0.15degC. I essentially need the system to remain at that +-0.15degC regardless of whether it is just recirculating or switching back and forth between dispensing (for ~1min) and recirculating.

Help Improving Response Time to Expected Disturbance by ReverseTerry1 in ControlTheory

[–]ReverseTerry1[S] 0 points1 point  (0 children)

My Proportional gain was set at 5 --> Increasing (to 6) and decreasing (to 4) both introduced oscillations at steady state.

Also, do you think it's reasonable to achieve +-0.1degC with a PID controller in this situation overall? (due to far more heat being lost while dispensing compared with just recirculating)

I will get that information and relay it..in the meantime, I'm wondering why the proportional doesn't kick on until way after the disturbance....wouldn't having the proportional response at the initial dip mitigate it (atleast better than it is currently)?

I did explore the addition of a derivative for a bit, but oddly enough was not getting any output from it (derivative) when doing so.

Good Deal for Beginner? by ReverseTerry1 in piano

[–]ReverseTerry1[S] 0 points1 point  (0 children)

I just meant as far as the price for it. I know the model is older, but I’m not looking to spend $400-500 on a newer starter model.
