Bad adhesion probléme after nozzle clogging!!

Hi every one and sorry for the bad English.
I got my geeetech i3 pro b since last week after assembly and some adjusting everting run smoothly and I was able to print different thing (using PLA), with some minor issue that i could resolve with repetier and bed leveling.
Then i was trying the filament simple send with my printer without knowing that its ABS so i got my nozzle clogged. First i was trying pushing hard on the filament to get it down and after i realize that it was ABS i get the nozzle cleaned ( using blowtorch), but after reassembling the nozzle everything went wrong.

1.i tired many many time to adjust the bed but either i have a completely squished filament or a non-adhesion at all 5 depending on side 5 adjusting the nozzle with the business card won’t help-.
2. one of the threaded road get stuck at the bottom of the Z axes near to z axes home (i have problem with this road from the begging the one supporting the X axe step motor) because i thing there is imperfection in the road plus the heavy load of the step motor and the extruder homing by its side).
3. the glass bed seem to be bend at the center.
4. the nozzle from time to time extrude a very thin line with a droplet in between.

I suspect that buy pushing hard on the nozzle while clogged by ABS i bend the bed and deform the printer parallel and perpendicular axes, so i will rebuild and check for the frame, for the bed i will try a flat glass to see if there is any improvement.
Any suggestion before dissembling the printer ?

I am also facing the same, Help is appreciated.

Thanks in advance.

Hi, You can view
1. Is the thread of your z-axis threaded rod normal or
The threaded rod is bent. If not, you can reinstall the threaded rod from the coupling;
2. You can check if the hot bed is level, if the unevenness in the middle will affect the printing;
3. You may still need to clean the nozzle. Your description is as if the nozzle is not completely cleaned.

I do have a similar fetching query at the point! Can bed-grip be influenced by spout type

I've as of late changed from utilizing a standard Prusa metal 0.4 mm spout to a P3D Apollo 0.4 mm spout.

In the wake of changing Z tallness a couple of times, I've discovered that bed grip (with ASA) is significantly short of what it was previously: the 16-hour print that I had printed effectively ordinarily prior to changing spout currently isolates from the bed at around 12ish hours into the print.

I'm utilizing a similar fiber (rigid. ink ASA), a similar warmth bed, and the equivalent code record is being printed so everything I can consider is that the 60% improved conductivity of the Apollo spout is some way or another having an impact. Will the spout conductivity affect bed bond or is it simply that I have to bring down that Z hub a few smidgens more?
