I know about the Leap Year bug, read all the thread.I have an AP900 mount I bought used��and it needs to have the hand pad updated, I am also aware of that.But, my mount was in my motorhome in the shop and I did not have the serial numbers to fill out the form and send it in, so I did not get��this done.However, I read that if you start the mount using the Ver2 driver and if you do not use Park 1 then it was not a problem.Well, I am up on the mountain and I have a big issue. I started everything like normal, using external initialization, my laptop. I have been using the mount for years and not a problem. But all seemed good, I did a recal on a star and then slewed on the East side to a star near Betelgeuse. All went well and I started CCDAP and it imaged until the meridian flip. Then when it flipped, automatically as always, it did something totally bizarre. It wrapped the cords around the mount, the thing turned a complete 360 in Dec and I��don't��know what else. I was lucky that I was awake and watching��on my remote laptop.��I normally never go out to see��if it flipped OK but for some reason I did this time and found the mount stalled with the Dec cable wrapped so tight that��it was almost impossible to undo.I managed to figure out how to unwrap all the USB cables and disconnect the Dec cable at the motor. Then I was able to loosen the clutches and tell it to��Park��at Park 3 and it moved the mount for a very long time and finally finished. The clutches being��loose allowed it to move without the scope moving. I set the mount with my levels and reconnected the cables and all. Then I restarted��all the programs and linked to the mount again. It unparked from Park 3 and slews to��a star in the north that I commanded from The Sky 6 and then Recal was successful.��Now it��would��go to the star which was now on the West side of the meridian. It also parked from there and��returned to Park 3.��So I started a new session and it went to the star, plate solved and focused and all is��seemingly working. However, I have no idea why it failed to do a meridian flip��and seemingly lost its way and wrapped the cords.

But maybe this is the bug and I just happen to find another problems with it.What I need to know is whether there is anyway that I can get the update without having to send in the��form to register. I don't have the ability to scan a form here so that I can send it to you by email.��I do��have internet access and cellphone.��What I need is help figuring out if this is the Leap Year problem and if so how can I fix it here so that I don't have to tear down and go home, it is a long drive and a big setup.

I discovered something vaguely similar over a year ago with an olderservo chip version.�� I forget the version but AFAIK, maybe it was"Q."�� I had��my��AP900 in the house and was��working onsoftware familiarization and had my��mount's tracking rate��set to"stop" tracking mode for several days.�� So anyway when I re-enabledtracking and told it to go to an object,��the RA��went completely aroundthree times before it stopped in the correct position.�� A bug was found byHoward or George and fixed and incorporated into the servo controller chipsshipped after that point.��If you have an older servo controller chip version then it might bethe same problem.�� Basically, leaving the mount powered up for multipledays but set to "stop" tracking speed.����When told to GOTO an object,it "catches up" by spinning the RA axis 360 degrees for every day��themount��was on and stopped.��Besides getting a servo controller��chip upgrade ASAP, the othersolution might be to��avoid leaving the mount powered up 24x7 and"stopped."��What servo controller chip version are yourunning?��Are you running the mount from the hand controller, from a PC or areyou sort of doing both at the same time?��I sure hope this all helps.����Christopher EricksonConsultingEngineerSummit KineticsWaikoloa, HI96738www.summitkinetics.com

Hi Chris,Thanks for the reply. Well I have not had the mount on with tracking stopped, I just set up that day.What ever happened it happened on the Meridian Flip. The Dec and RA seemed to have turned in the wrong direction after the move to the other side. This resulted in wrapping the Dec cable as well as the others wrapping around the pier. Normally my cables would be on the south side of the pier at all times. But this time the cables were wrapped around the north side. It just seems like everything was backwards.Strangely, after I reset the mount and slewed to the East side to get��back on target, everything worked fine and the mount parked after the session.Since I do not use my hand controller at all, I think I might leave it disconnected and see if that fixes this.��After all, you are able to control the mount without it. I would guess that if this works then the problem must be in the hand controller. I could just wait until I get back home and try to update it.Floyd��

#50917 Feb 6 12:12 PM

The issue is not in the hand controller since you had it set on EXT and initialized the mount via another program. In this mode the hand controller sends nothing to the mount servo and remains basically silent at all times. I have forwarded your post to Howard, who has more expertise on the older chips. You may need to get one of the latest chips for your CP servo controller.��Rolando����-----Original Message-----

Hi, thanks for you post.OK, I removed the hand controller last night and initialized as usual with the Ver 2 driver. Everything worked perfectly this time. SO I am sure that the problem was with the hand controller and most likely the Leap Year Bug.I just think it is a good idea for everyone to know that even if you use the Ver 2 driver and laptop to initialize and use Park 3, you can still have a problem with this bug. If possible you should remove the hand controller until you can update the hand controller. It is my opinion that this bug can wreak havoc even though you don't use the hand controller if it is connected to the CP.Hopefully this will keep others from experiencing this bug.When I get back home I will update my hand controller, then next month I will try again. But really I don't need the hand controller so I should just leave it off. :^)Floyd

#50939 Feb 7 12:22 PM

Thank you Marj, I will check my email. I am on the mountain now and with the hand controller removed the mount is functioning properly. I will handle the update when I return home.Thanks again,Floyd

#50941 Feb 7 1:21 PM

Hi Roland,I am not sure what to say, but when I removed the hand controller the mount works properly. I ran a session last night without it and the meridian flip and all went perfectly. If it is not the Leap Year Bug, I am not sure just what it could have been, nothing else has been changed and this was the first time I have been out this year. Last December it worked just fine.

I can assure you that I had the hand controller set for Ext Init, it has been set this way for a couple of years. Plus I have always used Park 3, never Park 1. Perhaps it was a glitch, that is possible, but if so then it is the first time I have seen this behavior with the AP900 in the years I have operated it.

I will update the hand controller when I return home. I don't want to try to mess with it up here at my astronomy site, easier to do it at home.Thanks,Floyd

Hi Floyd, ��Thank you for the information you provided in a private email. Based on the information we have for your mount on file, you have a very old chip in your GTOCP3control box.

Thank you, I will open the CP3 tomorrow and find out which chip it has and I will let you know that by email.I am already setup and ready to run, so I can't do that tonight.Thank you,Floyd

#50951 Feb 7 8:38 PM

Floyd,�������� No need to open the controller to identify the firmwarerev. The ASCOM V2 driver reads the chip revision and displays it in its header,just under the title,�� when you open the driver panel. Something whichperhaps a fair number of users overlook.��Joe

Marj,�������� I thought that may be the case. Although, even the wordBeta,�� isn.t flagged beside the chip rev. There could be the odd case,among perhaps other situations, where a mount gets sold with a beta chip, whichrequires the user to open the case to check.Anyway, I was just trying to reduce any possibility of confusion, when abug is reported.��Joe

#50985 Feb 8 1:25 PM

Hi Rolando,Thanks for the reply, yes my old chip had some bugs I think, I read the revisions. I thought it had a later chip than it does, but I am pretty sure it said "L" in the driver. Tonight I will take note of that. I will order the new one when I get back to the house. Plus I will update the hand pad too.This was the first time I had a issue, guess I was lucky!Wish I could just buy a new AP1100, but that is not to be. :^)Just the same, this old AP900 still works very well. Now if the damned wind would stop blowing I might bet some good data.I will also submit the registration form, so the mount is registered to me. The serial # is 900551 by the way, Marj had asked about that.Floyd

Hi Marj,

I have ordered on GTOCP4 from Mr. Baader. I hope you will send eraly also soon to Germany ;-))
