I got my G11/Gemini-1 used and PE was pretty bad (why the guy sold it), After properly adjusting the stock worm it started to shine. then the crummy $2 (yes the original servo motor cost $2 w/o encode

Maybe a couple more smart steppers, but maybe not as they look like 1.8 degree per step. https://www.kickstarter.com/projects/249504031/ananasstepper-30-a-servo-stepper-for-multi-axis-control?ref=nav_

I got the stm32 kit C, and I have say a few words: Quick shipment to California, excellent packing, assembled nice and quick. I am impressed with everything, great job guys. Now to the more difficult

Very interesting, will look more into this later today.

@ Howard, looking at your motor graphs, I am seeing at least 2 times and up to 4 times better positioning for the smart servo. Do you see the same or?

Good point, there is a dozen stores with under $20 on aliexpres, i think its so new there has not been many sales yet. If this proves to be a good motor/controller Here:

Under $20 for the smart stepper

I am very interested in the "smart stepper" results comparison. As I posted in the encoder thread, the price is close to the same (depending on the driver) (smart or not) 1. $14 stepper motor and $15

This some some serious professional work their guys! Well done!!!

I am a hardware guy, I dont really do coding (why I ask noob coding questions). That is why I posted the link to the F4 code above (.rar file), there is code for each item, like: 24Cxx ADC DMA IIC KEY

Yes, Aliexpress is very substandard to say ebay and banggood for customer support. AliExpress is a storefront (like ebay), But and a huge BUT, they don't referee the issues with aliexpress Stores (or

As I mentioned, I am going to try servo motors first (as i have them already mounted, so here is my next question: I will be using the https://github.com/misan/dcservo FW with arduino and was going to

I think the normal TMC5160 is $15 I think, so saving $6 for two by making two adapters is a question of time. Let us know how it works out. The new driver (forgot the number) is $20 each.

They been talking about it for a week or so in the news.

I see, thanks for the reply. When I use STM32 F1, F3, F4 (betaflight FW for drones), they all can store 100+ variables for flight control tuning/function adjustments. Is this not what you need because

Thanks for the reply. In another post, it "seemed" adding extra stuff (like encoder inputs) in the stm32 was "not" the direction of OnStep, maybe I misread what was wrote. Anyway, I have a few of the

For only $4, it has quite a bit more power the blue-pill Any interest from the devs or is it just too much work or not nessary, or? Stm32F4 EEdit link.

I found a box of stepper motors: 85x85x66mm 1.8 degree 2.4v 4.5a 56x56x75mm ?? (with driver) 42x42x40mm 1.8 degree 2.8v 2.0A (with encoder / driver) 42x42x23mm 1.8 degree 2.0v 2.0A (with encoder / dri

So comparing these two options are not very different in price: 1. $14 stepper motor and $15 tmc5160 drivers = $29, 2. $33 MKS-SERVO42B-Nema17-Closed-Loop-Stepper (the link I posted above to BG site),

Interesting stepper with closed loop, but $$$ https://www.banggood.com/MKS-SERVO42B-Nema17-Closed-Loop-Stepper-Motor-Kit-with-Display-Adapter-Board-for-3D-Printer-Part-p-1602157.html?rmmds=search&cur_
