Wowza. Even better deal 😀 Here are my notes from my "consew" digital servo controller. Based on my notes, I'm assuming the minimum speed is not adjustable, so my memory is probably wrong there. Default settings: U0: 45 | (Maximum "maximum" speed that can be obtained by using the arrow keys by end user) U2: 1 | (Reverse) U3: 12 | (No discernable difference, though the PDF calls this the "location parameter") U4: 0 | (Delay between pressing full throttle to when it instantly goes to full throttle.) (Note this is not the "slow start" I would prefer) U5: 8 | (No discernable difference) U6: 5 | (No discernable difference) U7: 0 | (Not adjustable) U8: 0 | (Not adjustable) From PDF that used to live here: https://www.consew.com/Files/112347/InstructionManuals/CSM1000.pdf CSM1000 Dual Display Controller Operating Instructions 1) The Speed Setting; UO Press R; Display UO, Press M to adjust; Display the number 5 to 70; {5 represents a minimum speed of 500 rpm, 70 represents the maximum speed of 7000 rpm}. Example 1: You need 3500 rev/min Press R: Display UO; Press M to adjust; Digital display 35; Press L to save. Example 2: You need 500 rev/min Press R: Display UO; Press M to adjust; Digital display 5; Press L to save. 2) Upper and lower needle position set; U1 Press R; Display U1; Press M to adjust; Display number 0 to 1; {0 for the next stop pin; 1 for the stop pin}; Press R to save 3) Reversing settings; U2 Press R; Display U2; Press M to adjust; Display number 0 to 1; {0 clockwise; 1 is the reversed}, Press R to save. 4) Location parameter setting; U3 Press R; Display U3; Press M to adjust; Display the number 8 to 20; (The smaller the number, the more slowly, but the positioning is more accurate; The bigger the number, the faster the location, the more not allowed), Press R to save. 5) Slow start setting U4 Press R; Display U4; Press M to adjust; Display the number 0 to 9; Press R to save 6) Other display instructions: {1}When the motor stall failure occurs, when it display E1, the motor does not work, press the R key to recovery; Many times, it is recommended to reduce the load or contact your dealer. {2}When the stream or under voltage fault occurred, when the motor display E2, the motor does not work, press R key to recovery, many times, it is recommended to reduce the load or contact your dealer. {3}When the motor has the Hall signal error, it display E4, check the motor and controller plus connection is intact, press R key to recovery many times, if not, please contact your dealer. 7) Restore factory settings: In the U mode, press the M button for 3 seconds or more. The set parameters are reset to the factory default state. ®

Congratulations! Can we get a good photo of the back of the machine? Specifically I'm looking for what attachment points the machine head has for a knee lift / foot lift. Having a knee or foot lift is quite convenient...worth putting in the effort to source/install one. I used to have a motor controller that said "by consew" like that. It had a minimum speed of 200rpm. If you haven't already, I suggest finding a manual for the motor controller and making sure the minimum speed is indeed set for 200. (Factory default is probably higher than that) Also, if you don't have a 45mm pulley yet, they are easy to come by, for example here: https://www.amazon.com/KKUANG-Industrial-Aluminium-Electric-Clutches/dp/B0DLGNBZFQ It will slow down your minimum speed at the hand wheel, and increase the torque at the hand wheel.

Maybe post a video showing how yours moves when that screw is loosened

That screw is a shoulder bolt with a very wide top. It appears to help constrain the plate that moves vertically when you lift the presser feet. That is, help prevent that plate from moving to the rear of the machine. (It has other constraints as well, which is probably how it's still functional without the shoulder bolt)

I would check if the machine is in time. And if it has a safety clutch, make sure it is engaged. If you can, make a slow, closeup video like Karbo's here to show the timing of your machine: https://leatherworker.net/forum/topic/131845-pfaff-345-issues/#findComment-784860 and post it for us to review

The knob that you turned increases the spring pressure. You can loosen that back up. To bring the presser foot down to a usable position, loosen the screw near the bottom of the spring.

Can you show a picture of what you adjusted to put the presser foot bar at its lowest setting?

It looks like you are missing a screw here.

This is normal. The extra work is going into compressing the presser foot spring. The effect goes away if you lift the presser feet. Mine does not lift as far when the inner toe is down. Maybe you aren't getting enough lift. Try pressing down with your hand on the far end of the foot lift bar and see if the feet will come up.

Missing lock nut? My singer 144 has a lock nut on that stud.

Genius!

Hear, hear! 🛠️

How about a close-up photo of the dial you are wanting to replace?

I did try to get the pin out...but the pin prevailed. Here is my "disassembly spread", inspired by @gottaknow's early post.

If you want equal lift, here's how to do it.

You could put a crescent wrench on the block to gently rotate it

That's in the ballpark.. Is the inner toe still lifting higher than the outer toe?

Can you post a link to Uwe's video, and post photos of the block you're trying to move?

Agree this seems weird. How much lift do you have now?

Depends on how hard you hit it I suppose.

So you can focus on buying a class of machine that does what you want, since you can fix it up. Most "fixing" is actually adjusting, with some cleaning and oiling along the way. I have bought a new hook for a machine where I broke the hook trying to get it out. But there were aftermarket parts available.

I haven't seen much good about the portable consews. https://leatherworker.net/forum/topic/111864-consew-cp206rl/#findComment-731591

I like that singers have documentation. If you buy a clone, you end up finding the documentation for whatever it was cloned from. The 211G is shown on this page: https://ismacs.net/singer_sewing_machine_company/model-list/classes-200-299.html Do any of the machines you're looking at come with a variable speed motor? That would bring the overall cost down.

The cutline looks interesting. Anybody know if a manual is available for those? I put in Asheville, NC and started searching. How about some of these: Tacsew gc6-6: https://www.facebook.com/marketplace/item/1217068313162876 Adler: https://www.facebook.com/marketplace/item/1256624485648626/ Unknown walking foot: https://www.facebook.com/marketplace/item/1411826190265789/ Nakajima: https://www.facebook.com/marketplace/item/1685486795446778

Post some photos of the machine.
