I am using gSender ver 1.4.12, using Windows 11 Pro [Version 10.0.26100.4484]. The CNC is a LongMill MK2, 48x30 Version: MK2. The gcode was generated by Vcarve Pro 12.5.04
When I am doing a 3D carving gSender frequently goes idle. If I use the GUI and restart the job from the line listed the speed drops to 2 inches per minute. I use the console and enter the last line, click run and the job resumes at the correct speed. This is what I usually see in the console

If I put the line G1X5.5455Y2.5795Z-0.4663 in, the job will never run again without restarting gSender. I am baffled by the � characters. Does anyone know what is happening and how I can resolve this? I’m thinking it is a communication error on the USB path. I am going to order the super longboard and connect using the Ethernet port to try and eliminate the issue.
I have had many usb disconnects before I replaced the cable that came with the machine with a proper usb cable (filtered, gold plated, shielded, the works).
Before that I made sure my pc didn’t put the usb to sleep after a certain time. You can set power savings usb to never as shown here:
I have checked the USB power settings already, and the PC will not put the USB to sleep. I am using the cable that came with the machine. I have also checked for anything that may put out EMF and there no device, light, transformer near by. I will go and purchase a different cable (filtered, gold plated, shielded, the works). Thank you for responding so quickly.
This might be displayed by Windows when the font doesn’t have a glyph for the character code it’s trying to display. I think it could be caused by EMI as @Spamming_Eddie said, missing or flipped bits yields a bad character code and the program or Windows displays � instead.
This just a somewhat educated guess on my part as to why you see so many of that glyph.
Unicode replacement character (U+FFFD). It appears when a system is unable to render a specific character from the data it is processing. This typically happens when the data contains a character that is not part of the system’s current character encoding or when the data is corrupted.
Thank you. Your reply made me look again. Cable is on the way. Gold connectors, Foil and Braid Shielding…
I’d have to agree with @_Michael, anytime I’ve typically seen these characters appear in the console, it’s a symptom of poor communication integrity with the board. Hopefully the replacement cable or switching to Ethernet should get you fixed right up
I ordered the USB cable (Gold Connectors 24K, Foil and Braid Shielding, Dual Ferrite) and installed it. I also change from dual 23" monitors to a Samsung Odyssey G9 49" monitor. The 23" monitors had power bricks that hung low and may have been a source of EMF. The Samsung monitor has the power supply behind the screen. This moved the monitor power supply further from the USB cable. I also have the same view as 3 screens instead of 2.
I also received the SLB today and will be installing it tomorrow. I will be switching to the Ethernet cable when the SLB is installed.
The problem is resolved. I want to thank everyone for the assistance.
I have that samsung in my office to have enough space for a few running cad screens, you run gsender on one -to reduce possible electric scatter from a power brick-?
Yes. The 23" monitors were way past their prime and really cause me eye strain. I had the Samsung in my office at home where it got little use. I was once in information technology. I needed the 49 inch screen until I was laid off. No, the company did not pay for the 49 inch screen, it came out of my pocket.
So, the monitor is back in action, no more eye strain. no possible EMF. I do run gSender. VCarve Pro (sometimes two instances), YouTube, and whatever else I need.
You could run your X from zero to the end, and have the axis taken over by its digital counterpart. I know you are a space hero, so this isn’t over the top at all.
The problem, sir, having such a monitor is, you can’t look at smaller ones and not see it as pfrrwrt. You become an elite smug, no matter how hard you fight it.
