Peter,

 

Add some weights to the CWT Shaft and slide them up…not a good idea to have them at the end.

Re: Through the mount USB3.0 on Mach2 trouble unrelated to temp

Terri Zittritsch
 

Michael, I dealt with this, being one of the first Mach2 users, and evidently the first one to try usb3.   The issue is likely all of the signal loss due to the number of connectors between your computer and hub, especially including those inside of the mount.     I identified the initial USB3 issue (turned out to be crossed USB3 wiring) and had to send the mount back for rewiring. Given I'm an EE in the custom semiconductor business, I have some peripheral knowledge of the limitations of USB3, so it makes sense to me.   
This was solved with an active repeater cable (it was for me) and I tested all kinds of cable lengths and ultimately I was limited to a 3' cable between the mount and my computer plus 1' cable between dec axis output and hub for reliable operation (which isn't acceptable for me).   I now have a 15' repeater cable with a small 8" cable from the repeater head (which is female) to the mount (male-male usb3 cable).    Then I use a short cable on the DEC head USB port to my cheapo hub.   My cheapo hub works fine to 0F and doesn't miss a beat.  While some vendors specify all kinds of industrial specifications for various expensive hubs, they likely have the same silicon inside of them.  They may have some better environmental sealing so if that gives some peace of mind, which is ok if you need it.   My hub is so cheap I've just purchased a spare and bring it when traveling.    So this works for me and I use several ZWO cameras, although I have a new 60MP camera that I've not tested yet.  But it works for an ASI071, ASI290, ASI1600MM.    I also confirmed that none of this had anything to do with the hub itself, because the same results could be had when bypassing the hub entirely as well as bypassing the mount pass through.

Re: Can I transfer a PEMPro PEC curve from a CP3 to CP4?

Ray Gralak
 

But the CP4 manual states "If you are upgrading to the GTOCP4 from an earlier control box, you cannot reuse
the curve from your GTOCP1/2/3. You will need to use PEMPro to generate a new PE curve for your mount.
Curves cannot be transferred from one control box to another, as they will end up out of phase."
This is the correct answer.

Re: At What Temp Do I Need 15V For My AP 1100 Mount?

Alex
 

As a side note, I make my own cables which is pretty easy to do.  I use Powerpole connectors on the side that connects to the AP1100 mount and I use ring connectors that I crimp onto 10 gauge wire on the side that connects to the LiFePO4 battery. At one time, I noticed some pre-made options on Amazon? Also, if you do not want to bother making your own cables Powerwerx allows you to design your own custom cable online and have it shipped to your home. Nice feature! Here is a link to the site: https://powerwerx.com/dual-conductor-custom-cable

Through the mount USB3.0 on Mach2 trouble unrelated to temp

Micheal Fields Jr
 

Previously I posted about cold weather issues because I made an assumption that my gear, namely my cables and hub, didn't like 47F.  However after trying to determine which cable, USB 3 port, computer and hub was at fault, there was one common denominator.  The cable going through the mount.

Roland offered some information about what happens when you have multiple cables connected.  Something about a reflection of frequency that causes interference... That kind of thing is honestly over my head but it makes sense.

So in a last ditch effort to isolate the issue and exclude the internal USB 3 cable I bought a 3 foot long female/female USB 3 cable for $10.00 on amazon and "pretended" it was the through the mount cable.  This way I would have an equal number of cable to cable connections.

As it turns out everything worked 100%.  No failures at all.    Then swapping back to the through the mount cable, errors nearly every other frame.

I also want to mention that I also followed Roland's suggestion of boosting/stabilizing the signal by putting a good USB hub at the base of the mount and then a 1 foot male/male USB 3.0 cable going from computer's USB 3.0 port to powered hub, hub to mount via 1.5foot USB 3 cable, mount to another powered hub, powered hub to camera.    The idea  being it doesn't go move than about 4 feet before it is in a good hub.  I had the same issues.

There is only so much I can do to make this work.  At this point I have to say the cable is bad and I've only had it out a total of two times for a combined 48 hours.    I am going to try some spray contact cleaner on both ends of the mount cable just in case there was some moisture related corrosion but I can't believe there would be this quickly.

Anyways, here is a link to a video I made showing what is going on. https://youtu.be/K5Xwe9NnYhU    So I am either going to have to use USB 2.0 mode only (plug it into a USB 2.0 port) or simply forego the USB 3.0 when I want to do planetary imaging with USB 3.

Kent,

I have used a Bioenno LiFePO4 battery for imaging year round with a Mach1GTO and 1100 mounts. I live upstate NY and in the Winter it is not unusual to reach 0F and occasionally below 0 temperatures. The battery is absolutely fine for all-night imaging runs even at those temperatures. An excellent case for LiFePO4 batteries is this one:

It has both Powerpole and cigarette plug connectors.

Re: Can I transfer a PEMPro PEC curve from a CP3 to CP4?

 

Hi Patrick

again weighing in without direct experience (although I've done this with other non-ap mounts)

when you re-create the curve from your existing data, you configjre PEMPro for the new CP4 then the new curve you create will be the correct resolution for that controller. CP4 is one of the options for AP

Re: At What Temp Do I Need 15V For My AP 1100 Mount?

Kent10
 

Thanks very much, Alex.  That is good to know and the LiFePO4 may do just fine for me in my cold.  The last few days I have been observing for a couple of hours each night in temps below freezing but still above 20 degrees.  I am using my old battery but at 12V instead of my usual 15V and all seems fine so far.  I'll keep using it like this for a while and if I don't have any issues then all must be fine.  I haven't heard from anyone else with issues at below freezing with 12V so maybe it is not normally a problem.  Or it takes much colder temps.

Next, I have to look into how to use the
LiFePO4 with the mount.  They don't have cigarette lighter sockets or Powerpole connectors.  Maybe an adapter with alligator clips like they have on the AP website?  https://www.astro-physics.com/accessories/mount-accessories/power-supplies/

Thanks again, Kent

Hi,
Subject already mentioned in early 2020.
https://ap-gto.groups.io/g/main/message/68026
Roland had made this answer.
"You cannot load the data directly from a CP3 to a CP4 because of the difference in the number of points. However, if you bring the curve up in PEMPro from the CP3, you can then use that created curve to load into the CP4. You can smooth out the steps and load it with a bit of finer detail that way.
 
Sorry for the confusion, I may have told George wrong since I did not fully understand how you were going to transfer the curve."

Patrick,

 

We are investigating a way to transfer the PE curve, but at this time it will be necessary to do a new curve.    It never hurts to have a fresh curve.

Re: Can I transfer a PEMPro PEC curve from a CP3 to CP4?

 

Hi Patrick

i don't have direct experience with what you're describing, but that description makes sense

you don't need to reacquire data, you just need to load the data you already gathered, create and output the curve (to a file), and then upload it to the CP4

This should take all of a couple minutes, it's not the same as having to gather the data

Hi Kent,

I use LiFePO4 batteries and the average voltage is higher than 12V. It is above 12.8V for most of its discharge curve. Here is a graph highlighting this nice feature of LiFePO4 batteries:

How to Find Happiness With LiFePO4 (Lithium-Ion) Batteries - Solacity Inc.

I'm from California so I rarely get into low temperatures to test the AP1100 mount but I have never had a problem with the mount when using LiFeO4 batteries so long as I do not deplete the battery below 10% charge.  Actually, I have never come close to depleting the battery to 10% when running all night.

Hello Karen,

Thanks for the status update. I didn’t get the email you refer to. I check my spam folder daily so it’s unlikely (but possible) that I have deleted it by mistake.

I don’t own another AP mount to play with at the moment (as other people, lucky folks) so I can’t say I’m not a bit disappointed but I definitely understand given the actual situation. Waiting is hard but it doesn't harm... :)

Stay safe and I wish you all the best at AP.

Hello Astro-Nuts,

We were trying not to throw Renishaw under the bus, but since Roland spilled the beans... Our Mach2 encoder shipment (both types) was delayed by Renishaw. They were forced to make operational changes due to the pandemic that set them behind. We can relate - we were unable to manufacture anything for 10 weeks in 2020 and we're still feeling those affects. Additionally, many more people ordered low-temp encoders for their Mach2s than we were anticipating, and some changed their order to low-temp after the fact. So our initial encoder order was not of the optimal mix to meet demand, and some low-temp encoder mounts have been delayed longer than standard-temp. Our subsequent encoder order, of course, would have corrected for this but as Roland mentioned, delivery has been delayed. Hence, we will have a stall in Mach2 shipments. With that said, we are still making Mach2s and not all orders will be delayed.

On a separate but related note, Renishaw is not our only supplier to experience delays. Over the holidays our anodizing subcontractor experienced a large Covid outbreak and was shut down for multiple weeks, which affects virtually every product we make. Frankly, we feel fortunate we've not had more issues such as these amongst our vendors, and have not had an outbreak ourselves.

We did send an update email to everyone whose Mach2 order will be delayed. If we missed you, please let me know so I can ensure our records are accurate. Thanks for your patience. These are certainly challenging times.
