Ah yeah, famous GX16 (16mm bore) or smaller GX12 (12mm bore), in fact they exists in all sizes and number of pins, so we commonly call them "aviator" terminals here because of their securing and shiel

I would avoid using same common shielded cable for both motor and sensor readings (I²C, 1Wire, encoders, etc). I'm using 4 wire shielded cable for each axis and separate shielded cables for sensors

GR1 is pully ratio, GR2 is worm ratio. RA: GR1 is 2.2625, GR2 is 130 DEC: GR1 is 5, GR2 is 65 Therefore: RA: (200*128*(42/16)*130)/360 = 24 266.66 steps/deg DEC: (200*128*(60/12)*65)/360 = 23 111.11 s

You should not do that unless you know exactly what are you doing. Some wemos d1 pins (if used) need to be pulled low during boot because they are used as special pins for switching bootloader modes o

Correct, but there is another thing you need to take care of: what's your motor max rpm speed and you should not exceed that. All calculation you may find in that excel spreadsheet. And also, very hig

#esp32 #maxesp3

I was refering to previous post which suggest using TMC2209. Since they are configured with only first two cfg pins (third one is used for decay mode) there is no configuration with same M0 and M1, so

#esp32 #maxesp3

On MaxESP3 not by default (I don't know what is MaxESP32 if that is even a thing) With MaxESP3 Only SPI drivers can switch mode on the fly since M0 and M1 pins are shared across axis1 and axis2 driver

Perhaps it's worth mentioning that because of this only 1/8, 1/16, 1/32 and 1/64 microstepping modes are available (which is fairly enough, Im not complaining)

It's not in program files but somewhere in user space, documets pethaps?

You have to place it in yor arduino library folder wherever that may be you can find in arduino ide preferences.

I also have onstepped CG-5 ASGT (15T : 60T : 144T) I found this to be sweetspot because any furthurer increase in angular resolution results in greather decrease in max GoTo slew rate than benefits in

But there is, it's still Ramps 1.4 build afterall. I thought about that for a long time but it's not worth. You need to replace mosfets with something like P30N06, do some modifications on ramps 5V pi

Only thing you can do is to try recuding max current by adjusting Vref trimpot on that driver. There is an option: #define AXIS4_DRIVER_POWER_DOWN OFF // OFF, ON Powers off the motor at stand-still. O

If I'm not mistaking, you need both BME280 and Adafruit Unified Sensor library

To connect standard AB encoders to wemos connect them as follows: Encoder 1 A to wemos D5 Encoder 1 B to wemos D6 Encoder 2 A to wemos D1 Encoder 2 B to wemos D2 You also need to supply encoders with

And one more thing, since you use Arduino Mega which is 5V logic board but HC-05 and Wemos D1 Mini are 3.3V logic board, you probably need TTL level shifter in between or you may render them unstable

Use only source from Git (not from addons!). If you have SHC and you want to have wifi SHC then use main branch, otherwise release branch will do. Take care of required library and board versions (2.4

BT it is known to cause problems with PC. I can use ramps build via bluetooth (which uses HC-05 bluetooth module) but I can't get MaxESP3 build to work with PC via bluetooth, no way. On the other hand

Just one more question, how dew heater feature know what is temperature of telescope if I do not have sensor other than BME280 which is nowehere near the heater element itself?

#dewheater #ramps

Oh, yeah, sorry for being stupid, now I think I understand. If I set Zero to to DP temperature and Span to approx. 5 degree above DP it will do PWM signal within this margin.
