The CP2 will work just fine for what you want to do. Rolando

I purchased a 130EDFGT years ago new from AP. I've used it with several AltAz mounts and a Tak EM200. I recently decided I want a GOTO mount, why not? Funds prevent me from a Mach 1, I'm not

We encounter similar situations with spikes and surges with the safety interlocks in the chemical process industry. I am not sure how sophisticated the CP4 controller program is (it seems to me to be

Mike, It is polyethelene foam. When I lived in southern California I was able to purchase a couple (giant roughly 4'x8') planks of the stuff from a local shipping supply

Sure you can but it might not blow. We tested an overcurrent system but ran into issues where the current exceeded the set limits during the start of a slew and sometimes gave false positives. We are

Rolando, On the matter of your work on a future CP4“over-current” limiter – would it be possible to use an appropriate in-line fusein the CP4 power cable? For example, using the

Thanks Roland. I appreciate the quick replies! joel

This is a perfect example why using APCC is the best thing to do for unattended imaging. It allows a second line of defense, in the event that the software you use for imaging fails. APCC never

The motors can still overcome a hand tight clutch. You need APCC and build limits. Your best bet for unattended. The only other way is a simple hour timer which has a 110 volt plug and will turn off

I was afraid it would be something like that. I'll call tomorrow to get it fixed. When the pier crash happened it was a (un)perfect storm of events that happened to cause the problem. Several things

Unfortunately, it appears then that the motor is toast and needs to be replaced. Apparently the clutches were tight enough but not locked so the motor could still turn but was drawing excess current.

Sorry, I did as you instructed and the motor shaft does not turn by hand. Powered off, power cable removed, disengaged from the worm gear. joel

That is no information. What I asked is for you to turn power off and turn it by hand. Does it turn when you turn it by hand or is the motor shaft frozen? Roland

Same result if you swap the connectors?

Unfortunately the motor shaft does not turn at all (RA). joel

neither of those will have anything to do with motor Stall. Howard and I are here at the office all night if you need assistance. Rolando

Remove the cover on the RA gearbox, the one on the side. You will see the geartrain and the motor shaft with small pinion on it. With the power off and the gearbox disengaged from the worm see if the

Yeah, latest firmware and latest driver. joel

Hey Joel, Do you have the latest firmware installed for the CP4? Should be VCP4-P01-11. Not likely related to your problem, but something to confirm. -Bill From: ap-gto@... on behalf of

I double checked the cables and made sure they were fully seated. The LED on the CP4 is green. I get the motor stall warning when the gear boxes are disengaged from the worm. I tried
