Hello Howard, i came across your project last Friday. I am really impressed! Well done and thank you for sharing it with us. Being an electronics engineer i really appreciate how much time and effort

Thank you for all your answers. MiniPCB would be nice but since I am in Europe shipping costs from the US would be too high. Also i cannot source any local company willing to make couple off for reaso

I didnt realize that. Checked the costs and it seem they will charge 12 euros for 10 boards including shipment by post. I think i will give it a try.

Thanks for your offer. I think i will be more happy with miniPCB :) 15 EUR they quoted is acceptable or my budget.

Thanks. I found the code and scanned through it. My understanding is that ESP-01 acts as a standalone board that provides all wifi services (AP, configuration and Onstep control via web interface) and

I am trying to figure out what the Microstep number in the Configuration Calculator xls should be set to. TMC2100 with CFG1/2 open should provide 16 microsteps and with interpolation up to 256 microst

I have 200 steps motors, TMC2100 drivers, Exos2 with 144 worm/wheel ratio and 60/16 worm/motor ratio. The calculator shows this: Does it look usable?

Does that mean that if 1.5A stepper is used TMC would drive it with 1A (lower torque than nominal)? It's not going to burn or something, is it? I have noticed that some steppers have specified Voltage

I have got few of these: https://www.ebay.de/itm/Heis-17-3D-Drucker-Zwei-Phasen-4-Leiter-Schrittmotor-fur-1-8Deg-17HD34008-22B/202270852095?hash=item2f184843ff:g:jP8AAOSwn8VZh9mn Do you think they mig

Geroge, thank you. My next question is: What is the most suitable material for the motor bracket? The options are Nylon, ABS, Carbon filled PETG, standard PETG and PLA. I plan to get both motor bracke

Got a reply from the 3d printers: they dont use ABS anymore. What do you think of Nylon? If it is no better than petg i will go for petg.

Just looking at the LXD75 bracket design. It doesn't take NEMA17 motors. Are Nema 11 strong enough for such mount?

Can you point me to the file location for your brackets, please? I only found Howard's LXD75 bracket files in Files section of this group.

Since this is going to be my first EQ goto mount i am going to ask a silly question. Is the declination axis being driven during tracking? I guess if the mount is not perfectly polar aligned OnStep's

Can I use these? https://www.ebay.de/itm/TMC2130-Schritt-Motortreibermodul-fuer-3D-Drucker-CNC-Gravur-D9L7/263523498634?hash=item3d5b397a8a:g:wSYAAOSw345alsfQ It says Fystec 1.0 - not sure what is the

Do you mean this? https://groups.io/g/onstep/message/1769 If it's only about removal of one 0R resistor i do not mind :) It might be even easier than reversing SPI headers on Fystec 1.1 module. Being

Actually, i found a better picture that shows what needs to be done in order to use Fystec 1.0 in SPI mode (as Fystec 1.1)

I am doing some rough calculations. Can you do a sanity check for me, please? I have stepper with 200 steps and holding torque of 0.5Nm. EQ5 with 1:144 worm/gear and 1:2.5 motor/worm ratio. I will use

Is it possible to configure ESP01 module as Wifi AP with WEP security? It seems the default is WPA2 and i cannot find in the source code how to change it.

When connecting the ESP in Station Mode to existing Wifi that uses WEP there is nothing to do and it connects just find. However, when setting up ESP as an access point there is no configuration to ch
