Re: Hacking the HP45

That really depends on what controller you are using and in what orientation you are printing the barcode.

After the first few posts (2-3?) you should be able to attach images. These images can not be any bigger than 512kB.

Re: Hacking the HP45

I have tried a (relatively weak) magnifying glass quickly, but I do not see any more than just the 1 dot. It also makes little sense to me how a single printhead that ejects ink through a single hole would make 4 tiny dots. With color on the other hand I can see how that could be. Each of the dots y...

Re: Oasis 3DP printer

From here on out I hope to do a weekly or biweekly update on Oasis. It is now moving at a pace where things are interesting. First I rewrote how the buffer that stores the print lines. The printhead has 2 rows of 150 nozzles and the buffer has one row of 300 nozzles. This means that if I want a stra...

Re: Oasis 3DP printer

If I use 2 processors in parallel I need to synchronize them to a couple of microseconds. While very possible, it is extra headache that is not wanted if it is not necessary. At this moment I have no real issues with the printer not having enough processing power. The SD read function should also no...

Re: Oasis 3DP printer

2 days ago I had the buffer, motion driver and inkjet driver, now I have this: CaOeG2SS8-E All functions on their own were working fine, but getting them to play with each other took more effort. The problems are mostly to do with the HP controller V1.01. For some reason it does not really like to t...

Re: Hacking the HP45

The head is common ground. All the pins drain to the same 14 ground pins on the printhead.

Re: Hacking the HP45

I haz presents In exchange for the HP C8855m documentation I got a carrier, HP C8855m and the stuff required to hook it up. This is great because of a couple of things. I now have an original carrier that I can base my own on. The current version is bulky and requires some cutting in the HP45 to mak...

Re: Hacking the HP45

Not really dropping it, but I have not yet found time to use it. The suggestion came after I had my own controller working.

Re: Hacking the HP45

Not yet, but the HP23 is roughly wired the same to the HP45, only more fragile and with less width to print (96 nozzles per color if I am not mistaken). Once the HP45 is fully finished I might give it a go.
