Error with RST-135 Slow Rate

#1

Post by stbkaiser »

Hi Robin
Seems I have another issue when connected to my RST-135 mount.
SC pro v 4.1.11351 64 bit
Trying to jog at the Slow speed RATE .27 , SC is throwing an exception.(Did not do this in the past, but not sure how many updates ago)
The 0.6 and 6.2 Rates do work OK.
attached is the zipped bug report file.
Thanks
Steve

Hi Steve,

I think we looked at this one before and didn't resolve it. I do seem to recall adding logging to check things more carefully if it happens again, and the current log contains that info.

From the log it looks like the ASCOM driver is wrongly rejecting a movement rate that it has advertised as being available...

Code: Select all

Info   	15:06:16.425558	#1 	Axis 0 has 3 slew rates.																								in Tuple<double, double>[] SharpCap.MountProxy.ASCOM.MountWrapper.GetSlewRatesViaIndexing(int axis)
Info   	15:06:16.428158	#1 	Slew rates are : 0.6-0.6, 0.26666666666666666-0.26666666666666666, 6.25-6.25											in Tuple<double, double>[] SharpCap.MountProxy.ASCOM.MountWrapper.GetSlewRatesViaIndexing(int axis)
Info   	15:06:16.448360	#1 	Axis 1 has 3 slew rates.																								in Tuple<double, double>[] SharpCap.MountProxy.ASCOM.MountWrapper.GetSlewRatesViaIndexing(int axis)
Info   	15:06:16.448519	#1 	Slew rates are : 0.6-0.6, 0.26666666666666666-0.26666666666666666, 6.25-6.25	

...

Warning	15:06:56.133616	#1 	Error from MoveAxis attempt with parameters Secondary, 0.26666666666666666 : Exception of type 'InvalidValueException' : unspecified 


You can see that the 0.26666666666666 value being rejected is identical to the one reported as available.

I really hope that the ASCOM driver is still being maintained for your telescope, since it seems that it needs some work in more than one place :(

cheers,

Robin
