Un-lobotomizing a Maho MH600T

Why you put exe 602 and not your ic-nv boards?
Can you share your configs and hal components for gears and spindle speed?

 Sounds like you spot on with you home made lubricator.Since the mechanical logic in the Willy Vogel system is dumb there is the possibility that the relief pressure to the tank may end up at a lower pressure than the controller pressure switch. It hasn't happened on mine though.The Vogel controller is very simple on mine. It only allows you to set the time between lubrication events. And it always does a cycle on power up. During commissioning my machine it dumped and the entire tank because of that. So I put a delay on timer on it to delay the startup cycle.It also has a mode where it will lube after a certain number of pulses are sent to it. So you could put micro-switches on the drive motors to count the slide movements and oil accordingly. My Heidenhain has the ability to count slide distance traveled, but I haven't figured out how to invoke that.Plus I would need to have 4 individual solenoids to deliver to my 4 axes individually as they reach the distance.BTW: the pump on the lubricator is a a cycloidal one typical of many cars. That's so the pressure pulsations are smaller and don't confuse the pressure switches.

Here is the big one. I split it using the print to file and custom page numbers. Hope it works

I have also your ic-nv circuit and had noise problems and voltage drop to 5v line that resolved by lowering the triac gate resistor.
For fuse can use a fuse with soldered legs because fuse pcb base can be problematic.
Noise problems resolved 90% by using other 5v power supply.
I think i will use ferrite beads to ic-nv boards 5v power cable or common mode choke and put
these boards inside grounded metalic box for the remaining noise problems.
Noise seems to appear when servo drives enabled that emit noise.

Thank you D Jensen for the manuals. They do appear to work fine. Unfortunately, right now I don't have the time/energy to go through them (long working days...), but will in the future. I appreciate it!

vre: Like you may have read a few posts back, I had all kinds of issues with the scales/interpolators. I did not want to turn this "restoration" into a interpolator project, so I thought I'd try the EXE 602 to see if those work without issue. At this current moment, I do think that my own interpolators would work fine. I never saw them missing a single encoder step/pulse, with the exception for the index pulse. And once I realized the voltage issue (because of the circuit breaker and also fuse), I only saw the vertical axis miss the index pulse. And as it turned out, I think that is an issue with the scale and not with the interpolator, as the EXE 602 also missed the index pulse every once in a while. It was more straightforward to "resistor bodge" the EXE 602 than my own interpolator. And after all time spent on this, I preferred to move on once everything seemed to be working properly. That being said, I do want to still use my own interpolators. But I will get the machine into a working condition before considering that.

Do you need the hal config and components right now? I did have a plan to share everything, perhaps on github. But I would still like to polish especially the components a bit. And also the configs are not really clean at the moment, since I still don't have everything setup properly. But if you needs something now, I might still oblige. At the very least, I will provide whatever setup/information I have about specific issues.

I know that your configs-components are not finished yet. I don't plan to use them as is just for ideas..Mine machine is very similar to yours.
I missed that heidenhain scales have index pulse.. Where this pulse is located at the start of scale where exactly? This is very good for accurate homing because now for homing i use regular switches that are not so accurate.
Mine machine has 2 identical spindles with gearbox that has 2 speeds and i want to put encoder for rigid tapping. Also lulbrication system is as your.
Mine has also 2 hydraulic cylinders for counterweight of knee table.
