Use the driver to do this as a last resort with no APCC connected. Then go back to your usual arrangement. The other option is to use your hand pad if you bought one with your mount.

Re: Running Mach2 from battery at 24v

Hello Sebastien,

All good points. That 5% loss in the boost converter would most likely turn into heat. In any case, if there are no benefits for normal tracking and guiding for imaging at 24V, there would be no point operating at that voltage.

Thank you for your response, unfortunately that option is not available for the Mach2. The only option is Last Park.

>>> My question is, is there any way to perform an unpark from park 3?,

yes - when you unpark in APCC, change "unpark from last park" to "unpark from Park 3"

Subject: [ap-gto] pointing error with keypad

Hi

I have an old (very old 1998!!) AP900gto, i encount some problem with
pointing accuracy.

When i use safari (with skybt) and slew for exemple between a star and a
planet (mirach and mars for exemple), all is ok, the two object are seen
in lot of eyepiece with my mewlon 210, when i do the same operation with
keypad, for the planet, the pointing is always off with the the eyepiece
but when i slew stars to stars, there is no difference between safari
and keypad.

Is there a probleme with time zone or else (i put legal time, timezone
00, daylight saving 0 at the moment), i live in west of france (about
1°25W), what are the good parameter?

Is there somewhere a corruption of planet database, i change the battery
few month ago, generally,  i found pointing is less good than it was
before...

The firmware is 4.19.

What is wrong with me?

Regards

Vincent

Re: Running Mach2 from battery at 24v

Sébastien Doré
 

Hi Steve,

If you don’t need to slew at high speed, you might not find a great advantage in boosting your battery voltage to 24V.

While it might seem appealing to get room as far as power is concerned, be aware that a dc-dc boost converter won’t give you much than what your battery can already provide. In fact, any voltage conversion (buck or boost) will result in loss of power in the system. Your load (the mount in your case) will consume about the same amount of power (more voltage and less current at 24V than 12V) but the inefficiencies (as small as they can be, say 5% like in the model you are considering) will be totally lost, resulting in a lost of autonomy of your battery-powered system.

Also keep in mind that some dc-dc converter designs require a minimum load to work (or start working) and perform at their nominal specified efficiency... So depending on what else you plan to power from 24V oversizing might not be your friend...

Clear sky!

Sébastien

Hello,

Preparing for a mach2 in the future, would anybody care to recommend (AP staff included) a good quality DC2DC boost converter for 12V to 24V? Reading the specs, it seems the mount may like to operate at 24V instead of 12V. In the case of operating from 12V batteries, looking at options. 

Looking at this one: https://www.amazon.com/DROK-Conversion-Efficiency-Waterproof-Transformer/dp/B081RFN1VJ

It's nice with much overhead for the current load /power required, good efficiency. Not that I'm planning on slewing at 1800x running from batteries :-) 

thanks,

Re: Running Mach2 from battery at 24v

Frank Widmann
 

When I run 24 volt stepper motors from a battery, I just wire two twelve volt batteries in series to get 24 volts. Motor scooter and wheel chair batteries are reasonably priced and durable.


Absolute Encoders status

Craig Young
 

What conditions/actions will cause the Absolute Encoders to go into the "Set" condition?

I have a GTO1600AE/CP4 and when I ran the APAE utility it showed the status of the encoders as "Set".  I changed that to "On" and now each time I restart the mount the utility shows the status as "On".  So somewhere in the past the encoders got turned off and remained in a "Set" condition.  Does upgrading the software do that?  Or, some error condition in the mount at startup?

Also, can we get some sort of indication on the ASCOM V2 driver what state the encoders are in (e.g., "Set" or "On").

Re: Mach2 Wifi problems #Mach2GTO #WiFi

Dominique Durand
 

Hi,
With Mach2 / CP5 I also have an equivalent problem. When the mount is connected to the PC via USB3 the CP5 network disappears from the networks visible on the smarphone and on the PC and for indication if I hold the antennas of the CP5 between my fingers it reappears. I have tried different combinations, but what is certain is that the CP5 / PC connection disturbs the WIFI hopspot of the CP5. I have no password worries and with the CP4 of my previous Mach1 I have never noticed this problem.

Re: Running Mach2 from battery at 24v

Thank you for the advice,

It will be cleaner to power direct from 12V battery, when imaging where AC is not available.

Re: Running Mach2 from battery at 24v

Hi Steve, I have been running my Mach2 on 12 v since I got it.  Actually, I have the power supply set to 13.5 v but a couple of times I forgot to turn the PS on and ran all night on the backup battery.  It works fine although I don’t slew any faster than 900x (for mapping runs) and I generally run the mount at 600x.

Re: Running Mach2 from battery at 24v

Roland Christen
 

If you are doing nothing but slewing, then it's nice to have 1800x. However, the mount runs just peachy with only 12 volts. In fact it will even run nicely at 10 volts. When you are tracking or guiding, etc, it doesn't matter what voltage you use, 12v, 18v, 24v. All works just the same.

Joe,

 

I do not think this is an issue with Ernie’s Windows system. Since the problem is manifesting on multiple systems (mobile device, Windows 10, and a Mac) it is more likely an issue with either the settings in the CP4 or a potential hardware problem. Often we find that general operating system changes, updates and incompatibilities are at the root of an issue, but the wifi issue Ernie describes is occurring on all operating systems.

Ernie,

 

    Which “Update version” of Win-10 are you running on (perhaps # 2004 ?).

 

    With deference and due respect to Bill Long, I have recently started having “system-erased password” problems connecting to the ISP, using my old Live Mail program, now periodically asking for my password on Win-10 Reboot, possibly under other situations repeating at a  later time, after I provide the same password again. Seemed to pop up at random during the day even without reboot, and reduced as  I started eliminating suspect apps. Never did that in the past. Something has changed in that wonderful update’s improvements, and I have been chasing the new culprit on a few PC’s  besides mine, for over a month.

 

    Check the location (or settings), where your password is “supposed to have been stored”,  to see if it is now blank, until you respond with it again and it gets automatically refilled there. Maybe your situation is similar.

 

     Windows Control Panel- User Accounts – Credentials is supposed to remember a specified password for some Application(s) and visited websites, which you can check by giving your Win-10 login password to open the hidden ones.

Or for your “named WiFi network”, check for the password under Network & Sharing Center – the Wireless Properties tab (for that WiFi network),  in the Security tab, to see if it got erased.  However, the latter has been untouched on my system, so far.

Re: Mach2 Wifi problems #Mach2GTO #WiFi

I have had this problem too. Very intermittent and not reproducible on command.

My solution is to simply cycle power on the CP4. No need to park the mount first, since the CP2/3/4/5's all have an awesome brownout power feature, they always remember where they  are when power is restored, absolute encoders or not.

Just cycle the power on the CPx and do a fresh GOTO to your target of interest.

Hi Ernie,

 

I have had this problem with my CP4 on occasion.  It will disconnect in the middle of a session.  If I try to reconnect, it asks for the password, but won’t accept it.  The only way to reconnect is to recycle power to the CP.  With my 1100 mount, I don’t have absolute encoders, so I park the mount with APCC and then reconnect and slew back to my object.  With the Mach 2, you can probably just recycle power without having to park because of the AE’s.

 

I have heard others with this problem as well, but AP says they can’t duplicate it.  I suspect it has something to do with outside interference in your area.  Mine rarely does it, so I can live with that, but it is annoying.

Hello all,
Absent the keypad, I've been using SkySafari6 and my iPhone as a hand controller, via WiFi, to nudge the field of view when centering objects for photography. I do this by first initializing the mount via APCC, which is attached to a Windows laptop via RS232. Up to now, it has worked. But today, during daytime testing of connections of the mount inside my house, I can no longer connect to the Mach2 via WiFi after initializing. My phone tells me that my password is incorrect. My Windows laptop also cannot connect to the GTOCP5 wifi network, even though it shows up clearly in my list of available WiFi hotspots (although intermittently). My Mac laptop, which did connect to the Mach2 via Wifi and SkySafari yesterday, is not able to connect to the mount.

I have not changed the CP5 from its default settings as a WiFi as a wifi broadcast point. I have not changed the password. It is not connected to my home network. My power is good, the red light shines on the CP5. The mount will run and talk to my PC via the RS232 serial connection. Given that I cannot connect to the CP5 wifi with any of my devices, I suspect a WiFi failure of some sort, or a password that somehow got scrambled without my intervention. Also, the CP5 hotspot will intermittently disappear from my list of available WiFi hotspots. Any ideas out there? Anyone else have WiFi trouble with their Mach2?
