PS I re-used the original CGE Pro RA and Dec cables. I connected the stepper motor wires from the controller board to a cable harness using a screw down terminal blocks and likewise at the motor side.

I have not tried PEC yet. It's wired but i have not yet even tried a PEC recording so i don't know if the PEC sense works. Might be a couple of weeks until i get to it. The PEC sense is connected to p

Thanks! Alignment in SP and SHC now works. I have read the “Using OnStep” wiki but didn’t appreciate that alignment has to be done immediately after power up as you describe above.

I have CGE Pro recently converted to Onstep using the MiniPCB2, Teensy 4.0 and TMC5160 drivers. I am having problems with the alignment procedure using either Sky Planetarium (SP) or the Smart Hand Co

Tom, the belts i used are 6mm GT2. The NEMA-17motors i have have 5mm shafts. I think this is standard for NEMA-17. It's the shaft on the Celestron worm gear that is 6mm in diameter. I bought the 5mm b

I have now a completed and operational CGE Pro converted to OnStep. The setup is: MiniPCB2 Teensy 4.0 TMC5160 drivers Stepper motors ROB-10846 Nema 17, 400 step, 1.7A/phase, torque 48N-cm 158 tooth be

Turns out the problem was the Dec motor was going in the wrong direction. I turned on AXIS2_DRIVER_REVERSE in config.h and home sense now works and the mount now points to the correct coordinates. The

I did add the resistor to either aux3 or aux4 as per the instructiond. This change allows the home sensor to replace a status led. Similarly, i did this to the aux0 status led so i could use it as a h

I think i have the config changes correct and match what you have. I am wondering if the HOME_SENSE_STATE might be the issue. When it says "HIGH, State when clockwise of home position, as seen from fr

I now have an operational CGE Pro and am running through some basic setup and testing. I tried to move the scope to “Home” but it just slews until it reaches a pointing limit. I tired this with the SH

I tried again with esp2866 version 2.4.2 with LOLIN (WEMOS) D1 R2 & mini. This time i set the Arduino IDE to Erase Flash: "All Flash Contents". I also reverted to the default Extended-config.h file (a

I have a wemos mini D1 pro with a minPCBv2. After uploading the Smart Web Server FW to the wemos min and then inserting it into the miniPCB2 onstep controller, i don't see the ONSTEP SSID being broadc

Thanks. Nice to have a known reference point to start from. I think i will start with TMC_SPI OFF and try it later once thinks are verified and running.

Can someone suggest some reasonable values for the driver currents in the config.h? CGE Pro, 1.7A stepper, GR1 1:4, TMC5160, 24v power supply. This is what i am guessing at for now (same for axis2) #d

Thanks all. a bit more soldering and I’ll be ready to go.

The MiniPCB has 3 wires for PEC : ground, 3.3v and PEC. The PEC board in the CGE Pro RA motor enclosure has 4 wires. Can anyone tell me which CGE Pro PEC wires connect to the 3 MiniPCB wires? Stephen

I am planning on using the Aux0 (pin 19) on the MiniPCB2 to read the input from the mount's limit switches. The pinmap and code appear to support this configuration. However, Aux0 does not have a capa

Never Mind - lol? I found it and order the board.

I apologize in advance for this question... I want to buy the miniPCB2 from EasyEDA, but i don't see buttons to click to actually buy it. I expect i am missing something obvious, hence my embarrassmen

Similar specs so hopefully the torque is sufficient to move the sticky dec axis on my CGE Pro. I will be using a 4:1 reduction with the transfer belt. Thanks for the other parts sources. Stephen J McI
