@michael-petitclerc , thanks so much for your assistance.

@larsbrubaker , thanks for your reply. Attached you shall see a pic of my desktop with MatterControl version 2.19.1.10116 which I just upgraded to.

As you see, the middle panel is not displaying correctly.
Thanks in advance.

@michael-petitclerc , the filament I'm using is from Monoprice, Premium 3D Printer Filament PLA 1.75mm 1kg/spool. I've been using this filament for over a year without any problems.

I don't use any adhesive on the glass plate because I don't have any sticking or warping problem since I increased the bed heat to 70 degrees C. Sometimes parts that take up a large amount of the bed space I'll spot glue corners and mid-points to prevent warping. But that's the only time I will use an adhesive.

I wish MC would continue updating MatterControl 32-bit.

After re-flashing the printer and making changes to the Extrusion Multiplier (Tuning Adjustment) from 1 to 2. Adjusting E steps per mm from 95 to 100 and slowing ALL speeds down by 20% and the fisrt layer down 50%, and the fan to cool the plastic in the rear of the hotends. I get this print. When I tried to make another print, the filament doesn't stick to the glass plate and accumulates on the hotend. I can't figure out why I the printer just doesn't duplicate a print when no changes have been made. I'm glad I look at this as a "fun" hobby, otherwise I think I'd be going crazy ... LOL!

I tried re-calibrating the extruder using the steps from the link you sent. I got a weird result (I think). I checked the extrution distance 3-times using the 120 mm constant length. My extruder extruded 20mm of the 120 mm each time, consistently. Below you will see my parameter screen. Then I tried just a couple guestimits but increasing the E-Step but +10 mm and there was no change. I check the printer memory to check if the changes were actually taking place and they were. (PS: no problem, we all have to take some time away, hope you enjoyed your time. )

Just out of curiosity, with the second fan that I attached, could that be affecting the print? It is running at 100% speed and I don't know how to control it in the Marlin software. I have the fan connected to the FAN2 on the GT2560 ref A controller board. Another think, I keep forgetting to include is that I'm using MatterControl version 1.7 - 32-bit because I don't have a 64-bit machine.

I checked the filament diameter to insure it was set for 1.75 mm and it was. So, I decided to slow the print process down. I set the Infill to 75% and decreased the speed to a total of 30% slower and the results are as shown in the image below.

Hi Michael.petitclerc,

Sorry took so long but I tried what you suggested with the fan but things got worse. Plastic wouldn't stick to the glass from 1/2 way on layer 2. So, I was reading one of the comments for updated slicr3 that they were having similiar problems and had to redue the firmware of their printer. I tried that but didn't work. Attached you will see what is happening. I've tried changing the parameters in MatterControl but nothing seems to be working. I'm a novice with 3D Printing and trying to learn the ropes and have fun with this but I think I might have screwed something up and can't get back to where I was getting good prints. Here's a picture of what I'm still getting.

Hi michael.petitclerc

Thanks for the suggestion. I'll try that but first I need to get a second fan to mount on the back side. When I get this and install it I'll let you know how the prints come out. Thanks again.

I'm have a delima with my print. The right rear of every print looks like lattice work while the other sides look ok. This is consistent with my prints. I first thought it was moisture but when I opened a vacuum sealed real of PLA I get exactly what you see in the pictures. This started right after I printed a nice looking elephant. Any ideas? Thanks in advance.
