Zero G 3d Printer

[Jomega Gibson]

ThePrintronix P8000 Zero-Tear offerings are specialized cartridge line matrix printers designed for businesses using multi-part and serialized documents that require print on demand, single form tear-off usability. The Zero-Tear functionality allows users to eliminate forms waste and reduce operating costs. Through its unique tractor configuration, the ZT models push single or multi-part media through the hammer bank and eject it up to the tear bar upon job completion. Configurations and printing speeds ranging from 500 to 1,000 lines per minute

Answer: The P8000 / P8000 Plus series are ideal for manufacturing, healthcare, distribution & logistics, food & beverage, automotive, government, and banking enterprises that need to print single or multi-part invoices, product shipment and transportation documentation, reports, statements, labels, and more.

Answer: Yes. For higher volume applications, the P8000 Zero-Tear model could potentially serve as a suitable replacement for serial matrix printers. Printronix also offers our S809 and S828 serial matrix printers which serve as superior plug-n-play alternatives to legacy IBM, TG, Printek, Epson, Oki, and Dascom printers.

Question: How does line matrix cartridge printing compare to laser printing for industrial applications?

Answer: Line Matrix Cartridge printers offer significant benefits over laser printers in terms of energy savings, cost per page, reliability in industrial environments and media flexibility (multipart forms, oversize media, peel-off labels or card stock). Every aspect of the line matrix printer is designed to deliver higher reliability, fast throughput, and greater resistance to rough handling and hazardous environmental conditions. In addition to energy savings, and substantially lower consumables cost, line matrix printers also have a much longer life cycle than laser printers. When you factor all these elements, line matrix provides a substantially lower total cost of ownership over the life of the product.

Answer: For the following reasons, Printronix Line Matrix technology is definitively the most sustainable high-volume printing solution available. 1.) Longevity: The average life of a Printronix Line Printer is 7-10yrs, whereas the average life of a business laser printer is 3yrs. 2.) Consumables waste: Printronix P8000 Cartridge Ribbons consist only of a plastic case, manufactured with 100% recycled polymers, plastic gears, and inked ribbon fabric. Laser printers generate substantially more consumables waster in that toner cartridges and usage kits require far more physical materials, chemicals, and packaging. 3.) Energy consumption: Printronix Line Matrix printers consume around 30% less energy than business class laser printers. 4.) Fine particulate emissions: Unlike laser printers that generate fine particulate emissions during the process of melting toner onto paper, line matrix printers emit no fine particulate emissions, and therefore, yield a safer environment for those working in close proximity to the printer.

Question: What remote printer management capabilities does the P8000 / P8000 Plus series offer?

Answer: Printronix PrintNet Enterprise remote management software provides remote visibility to printer status and ribbon life for every printer on the network, in addition to allowing for remote downloading of configurations, firmware updates, and resource files to multiple printers simultaneously.

Question: Does Printronix offer an extended warranty?

Answer: Printronix offers various extended warranties and maintenance contracts. Please contact your local Printronix sales representative to see what choices are available in your area.

Question: Are the P8000 ribbon cartridges backward compatible?

Answer: Yes, ribbon cartridges for the P8000 are backward compatible with P7000 printers, offering you reduced inventory management costs and simplified ordering.

Question: What is the page yield for the P8000 cartridge ribbons?

Answer: The Standard Life cartridge page yield is 17,000 pages and the Extended Life cartridge page yield is 30,000 pages.

Printronix understands that within the food & beverage industry mission critical printing is demanded across a wide range of environments from the loading dock to refrigerated areas within the warehouse. Printronix Line Matrix printers are designed with this in mind; engineered to deliver non-stop performance and withstand humidity, temperature, static electricity, dust and other airborne particles which can lead to premature failure, frequent paper jams, print quality issues and more.

Did you set your z endstop to the bed? You should not be using paper or a business card or whatever people keep using for some weird reason. z zero should be touching the surface of the bed. When you start your print it will move up all by itself to were it needs to be.

Your speeds are kind of all over the place. Large changes in speed will cause globs of material from the pressure difference. Stick with a 50% speed first layer, 10% outer wall and top layer reduction, possibly a 10% increase for infill.

As an aside, I installed all this on Raspberry Pi Zero with a USB Mini Hub with OTG

from Adafruit: www.adafruit.com/.../2991

The EDUP wifi dongle and the usb printer cable are both plugged into it.

I think means that a non-wifi zero will work just fine. It has for me so far.

so I was not getting on the wifi network. Coincidentally, another PI on the network somehow showed up with two IP addressed when I scanned the network for devices, so when I thought I was on the network but couldn't log in, it was a different device.

I bought a Rapsbery Pi and used the Octoprint image provided by Prusa. The Printer hat the latest Firmware 3.4.1.

I followed the instructions in +Preparing+necessary+components/585?lang=en . I plugged in the Pi on the board and switched the printrer on.

The Pi bootet up and I saw on my WLAN router that the PI got a IP address via DHCP. The printer bootet normal and I could enable the RPI port.

But I wanted to properly close the enclose and turned of the printer once more.

When I switched the printer on again it did not boot. There are only those 2 bars on the screen.

I removed the Pi and everything worked again. So I thought the Pi might have died and powered it up by USB. The Pi boots and I can log in by SSH and access the Octopi WebUI.

When I put it back in the Printer, the printer wont boot and show only this screen again:

After checking everything by eye, I could not find anything wrong. Then I decided to resolder every pin on the raspberry Pi. And hey, I did solve the problem.

But just from looking at it even with a magnifying glass I could not spot the bad welding.

A cold solder joint can be hard to detect without experience and even then if I am working with a board of unknown provence I will touch each joint with a hot iron to observe proper wetting out of the joint.

They can also slip through QC and pas a bench check and fail in usage by the end user... one of the earsons high end electronics vendors will perform a "burn in" is to circumvent this sort of infant mortality.

The pinda is a good example of how an item can be built to a price or service life... the vendor accepts that at a certain point it becomes uneconomic to reduce failure in their device to less than one in 10,000... as long as they pass the QC check at the end of production at that hat rate or better they continue to ship (for a proximity sensor like this I must assume they are also checking if it triggers within an acceptable range, in some places that make this sort of thing QC will actually be preforming a sorting function with devices that trip in a very narrow range close to a tight specification ) will be sorted into an AAA group for the fussiest customer and others would be sorted into A, B, and C batches. then the outfit must decide what level of performance he can afford to source for his machine or device.

I do not waste my time on the Zero option. It is underpowered. The one I bought before my Mk 3 arrived is still in its box and both my machines now work very well with Pi3b's connected externally via USB. Another new Mk3 feature that was not fully tested and is in fact pretty useless.

-longer time to boot octoprint

-ZERO = slowly octoprint than on RPI3 (update, seting etc all is slowly than on RPI3)

- You must buy extender for RPI cam cabel and long cabel to put camera on place without vibration of printer

First: I tried reseating the zero a number of times and eventually it booted and I configured up PrusaLink and PrusaConnect. I then turned off the printer and went to bed.

In the morning I return to the "two lines error" on start up.

I was concerned my pins were not long enough so I printed a shield for the Zero that was 1mm close to the main board (but still fully insulated). [I just sliced off the bottom 1mm in PrusaSlicer]

However that did not fix the problem, so with the advice of this thread...

I started lifting the pin header strip from the front side of the board to examine if the solder had run though and as I did so one of the pins came with the header - that is the pin was not soldered properly.

I reSoldered that pin
