I've just about got used to operating my EQ3-2 by its flexible manual control knobs but I'm increasingly aware of the wobble I introduce each time I adjust them them. So I would seem to be a natural candidate for a set of SW motors. However I don't want to spend £90+ for some 6 volt motors which have a reputation for blowing up hand controls and eating up batteries. I have read the AstroEQ (excellent piece of work by Tom Carpenter!) thread in this DIY section which offers a very attractive pathway towards full control and go-to tracking of the mount. I am therefore particularly interested in avoiding the SW motor drives and making use of some stepper motors with home constructed brackets as a first stage modification. But is there any way I could do this and control the motors in a semi-manual way without needing always to use a laptop running EQMOD etc? In other words, for instance, could a version of AstroEQ be interfaced with a manual control box (especially IR linked) driving stepper motors and offering simple object tracking? I started this as a new topic because I have some difficulty navigating within the AstroEQ 20+ page thread and don't want to distract.
Hi guys Anyone out there got an EQ5, AstroEQ and EQMOD and successfully guiding? The EQ5 is important here (not an HEQ5 or higher), because you'll have the dual axis motor kit and be ASCOM pulse guiding and not ST4 guiding. If so, it would be good to exchange notes so that I can hopefully get mine going. Might save me an awful lot of time experimenting and ultimately failing! Thanks
I have several parts, motors, and an arduino based AstroEQ controller that I don't use and maybe they could be useful to someone else. Btw I currently live in Turkey and I will ship everything with registered post from here. It should take approximately 2-3 weeks to reach to UK or other parts of Europe. I can accept payments from Paypal and also UK bank transfer. First, I have the arduino based controller. I have put it in a plastic project box. Pretty much everything is connected by jumper cables and the stepper drivers are on a breadbox. So it would be possible to change the casing or the individual parts rather easily. The DRV8825 stepper drivers are fast decay modded so they won't jump steps with lower voltage motors. I have installed the latest firmware that Tom has put on the website. If you want I can also adjust the voltage on the drivers before shipping depending on your setup. I'm asking £20 for it and £7 for shipping. Next I have two nema17 0.9 degree 6V 0.8A steppers. I have attached RJ11 female jacks for connectivity. £15 each and £7 for shipping. Both of them are sold. I also have a Nema14 1.8 degree 4.6V 0.8A stepper. Again I have put a RJ11 female jack. Price £10 and £5 for shipping. I've two handmade motor brackets for EQ5 (or equivalent) mounts. One for Nema 14 motors and the other for nema17. I have used the nema17 for RA and Nema14 for DEC. I'm asking £7 each and £5 for shipping. I have GT2 pulleys and belts. Two 40teeth and two 16teeth. 40s are bored to 6mm and 16s are 5mm, so they will fit the EQ5 worm and the stepper motor shafts. That would make a gear ratio of 2.5. I've included two GT2 140mm belts, which worked with my setup by adjusting the space a bit. I'm not willing to split this as the shipping cost would be more than the parts. As a whole I'm asking for £15 and £5 for shipping. Sold Finally, I two 2 meter cables with RJ11 jacks. From my experience when the standard thin phone cables are too long sometimes the motors don't function properly. Hence, I've used ticker cables with these connectors. £10 for total of two cables. £5 for shipping. If I ship multiple items together it will be cheaper. I'm also open to offers. And please ask me if you need more info.
I seem to be struggling getting the co-ordinates right in EQMOD Mine are N 53.XXXX,E -2.XXXX Do I enter it as -2 and select E or do i enter it as 02 or just 2 and select W??When i select a target in CDC it either points in the opposite direction or at the floor I've tried all manner of variations,none of which seem to work? Any help much appreciated
