Hi Gary,
that I had with my Atlas mount. I have seen some unusual behavior a few times but,OK, let me know if you see anything as I think I have discovered a few bugs in the PHD2 code. Unfortunately the PHD2 developers have been difficult to work with so I have corrected the bugs in a private version. I think my version should improve autoguiding performance but I need to test under clear skies (which have been hard to come by this year in Silicon Valley!). Thanks for all of your work to support your products.

Re: Need conterweight shaft advice
Woody Schlom <woody@...>
Donghun,
I have
the larger diameter CW shaft on my Mach1 and like it very much. It's
shorter in length but much thicker in diameter -- and it takes the "standard" AP
counter-weights instead of the smaller Mach1 weights.
The
standard AP weights come in many more weights and versions. I have two 10
lb. weights, one 18 lb. weight, and one 5 lb. weight. I prefer using the
single 18 lb. weight except that it's so much heavier and harder to lug around
and store. So when I setup at home in my back yard, I usually use the 18
lb. plus one 10 lb. plus one 5 lb. But when I'm in the field, I leave the
18 lb. at home and use two 10 lb. plus the 5 lb. Because my field
configuration is lighter, I have to slide the CWs further down the shaft to
balance everything.
Note
-- the standard short and thick CW shaft does NOT fit inside the Mach1 for
transport. However that's fine with me as the stripped down Mach1 is near
my carrying weight limit anyway. Add a heavy CW shaft and I might have
trouble lifting it.

Re: EXT startup only works via Serial Port?
Rick Thurmond
Thanks Roland,

I like the solution of setting Autoconnect=YES. The mount is now in a real observatory on a pier, so there is no need to leave it at NO like I used to. Then I can transparently run it with the keypad or TheSky. Rick

Need conterweight shaft advice
Donghun
Hi guys I'm currently using three 9lb counterweights and they are currently haning closes to the end of the 1.125" shaft on my Mach1GTO. To reduce moemtum arm, I'm thinkg of adding another counterweight. I'm wondering if I should switch to M1053-A 1.875" shaft instead or just add another counterweight to the default 1.125" shaft. Thank you very much. Donghun

Re: EXT startup only works via Serial Port?
Hi Rick,
I will bring my MacBook Pro from home in to work tomorrow (I’ll try to remember!) and see what I can figure out. There are no such restrictions on the GTOCP4 side, but TSX may be treating things differently. I am assuming that you have installed the FTDI Mac drivers from their website?? With that accomplished, the USB connection is really just a serial port. It should be no different from using a Keyspan USB to serial adapter.
Can you open the GTOCP4’s internal web page from your Mac?
I have verified that TSX’s Ethernet connection works on my Win7 – 64 system here at work. It initialized the mount properly. The initial connection and startup took a little while, so be patient.
Be sure you have the correct IP address for the GTOCP4, and be sure you are set to use Port 23 in TSX.
Our servo engineer is also a Mac user at home. He most assuredly designed the GTOCP4 to work on a Mac!!

Re: EXT startup only works via Serial Port?
Roland Christen
Howard will answer in more detail about your particular setup, which I am assuming is a Mac computer. As such you are not using the ASCOM driver, so you are limited by what the SkyX can do via the Ethernet connection (note, there is no limitation on the AP equipment).
toggle quoted messageShow quoted text
If the SkyX cannot properly initialize the mount via the Ethernet connection due to some limitation of that program, then I would recommend that you simply leave the keypad connected and set it to Autoconnect = YES. This way the keypad sends startup info to the mount and allows your external planetarium program to control the operation of the mount. You can then go anywhere with the SkyX and park it with that program at the end of the night. Next time you power up, the keypad will automatically resume the mount from that last parked position and you are good to go again with your Ethernet connection. Rolando

Re: MACH1GTO Gear Mesh Question
gary imm
Ray,
I appreciate your inquiry into my experience using MACH1GTO with PHD2. I have only had the mount for 2 months so I only have about 30 hours of experience with that combination. Generally I have seen good, consistent performance. I usually am able to achieve anywhere from 0.5 to 0.7 RMS arc-secs, which is better than the 0.7-1.0 that I had with my Atlas mount. I have seen some unusual behavior a few times but, like I said further up this chain, I can't rule out that I might have had a bad calibration. I am a bit of a stickler on trying to fully understand unusual behavior before waving a red flag, and in fairness I cannot say that I have confirmed any unusual behavior with PHD2 to date. Thanks for all of your work to support your products. In particular, I have been very impressed with APCC's Meridian Tracking Limits ability. I very rarely have to do a meridian flip in the middle of my imaging sessions any more, which has saved me a lot of time. Clear skies, Gary

Hi Ray , Initially I had problems with PHD , it used to be erratic . The problem which I think have discovered is my dependence on RAPAS and my living close to the equator . When seeing is bad I'm off by more than 5 arc minutes; secondly there is an option called guiding assistant which one must run for 10 minutes and it will tell you the settings . If I did all this I have no issues Suresh

Re: MACH1GTO Gear Mesh Question
Roland Christen
Ok, well give it a try and be sure to note the parameter numbers that you get after the calibration run. And always guide at 1x.
toggle quoted messageShow quoted text
Also please note, when you are adjusting that lever you are not setting the mesh. The worm gear is always in mesh, even if you fully loosen the lever and remove it from the gearbox. That lever simply sets the backstop. I hope the instructions don't say that you are setting the mesh when you are adjusting that lever. If so, then somebody made a mistook and we will fix that pronto ;^) That lever has two functions. 1: if you turn it fully counterclockwise to the left, the internal mechanism lifts the worm off the wormwheel so that you can critically balance your mount. 2: if you turn it clockwise to the right, the internal mechanism releases the worm so that the springs can push it into mesh with the worm wheel teeth. Turning the lever further until it stops, engages the backstop just above the worm mechanism so that the worm cannot back up by more than .001" or so. This slight clearance allows the worm to ride on the worm wheel in full contact through any low spots or high spots on the wheel. The springs always push that worm fully into mesh everywhere on that worm wheel. Rolando

I didn't fully understand how the lever assembly interacted with the worm wheel from reading the manual.
Every time I make an adjustment to anything in my optical train, I recalibrate in PHD2 since it is easy to do and takes relatively little time. It could very well be that I just had a poor calibration for some reason, which coincided with my adjustment of the gear mesh. Again, thanks for taking the time to write a detailed response.
