G Code - Image to Halftone GCode or DXF - DXF Halftone 2.1 or Halftoner 1.4

DXF Halftone 2.1 and Halftoner 1.4 are related, in that DXF Halftone was the inspiration for the slightly slicker Halftoner 1.4. Both utilities address generation of 'Halftone' GCode in very similar ways. Both create halftone toolpaths using dot or line based methods. Both can generate output as DXF.
DXF Halftone 2.1 comes with detailed readme and source code is included.
Some 'found' video of example cuts is included.
Additional image processing software called 'Reactor' is available at Jason Dorie's site. Reactor processes an image, using a reaction/diffusion system to 'grow' a unique pattern representing the image content. Output from 'Reactor' is a bitmap, that requires vectorisation to create a toolpath.

Hi again, Just to say I've checked the wayback machine links to DXF halftone 2.1. They do work.... would suggest getting it while it's still there. Hope this Helps

Hello there. We tried to do what you did. Uptade When we pressed the prewiew key, it is off the program. What could be the reason for this?

[@cncfreeorg]

Hi there, Do you mean you have a problem with the down load link... i.e where it says updated link ?? or Do you mean you cannot preview the effect of the setting adjustments in the software ?? if the problem is the download link... the original download link for DXF Halftone 2.1 did die.. so I found a wayback machine link... but this has now died also... it can still be found if you look carefully.. but I'm not updating the link here... in case it dies again. If your problem is using the software... then I can only point you back to the video... as this pretty much demonstrates whatever advice I might be able to offer... Hope this helps

what types of v-bit cutter, sir !? can i chose 60 degree

[@cncfreeorg]

Hi there, Sorry for the delay responding to this... I've been busy working on some new content for the channel.... There is no option to set or modify the v-bit angle but this doesnt mean you can't use a 60 degree bit.... To get a similar result to the preview using a 60 degree bit you would need to increase the depth of cut by about 80 percent (approx).... I should say I haven't actually tried this.. it's based on comparing the tool diameter of 90 degree and 60 degree V-bits for a given depth. Hope this helps...

ola amigo preciso fazer 50 mil chaveiros de 6mm x 6mm do escudo do flamengo no mdf de 6 mm , qual maquina saira peifeita pronta p entregar pro cliente ,a laser ou a de fresa ? tenho o prazo de 50 dias p entregar qual solução vc me indica parceiro?

Translation:- Portuguese to English - Google Hello friend I need to make 50 thousand keychains of 6mm x 6mm of flamengo shell in the mdf of 6 mm, which machine will you get ready to deliver to the client, laser or strawberry? I have the deadline of 50 days to deliver what solution you tell me partner? Reply:- Hi there, if the translation is correct you have challenging task. Unfortunately, there are too many unknowns to provide any real answer. There are some things that should guide your decision and I can speak to those a little more meaningfully. For example.... A timeframe of 50 days for a quantity of 50 thousand items.. (47 days by the time I'm replying). (47 x 24 x 60 x 60) = 4060800 seconds / 50,000 = 81.216 seconds per item If you manage to sleep eat and do everything else in say 8 hours per day... and with no days off... then this cuts the per item time down to approx 55 seconds per item.. and the job would take about 47 days.. with no allowance for failures, stock defects breakdowns or any other problems. The actual amount of stock you would need to process is about 1 and a half sheets of 'standard' 1200 x 2400 mm MDF. Without seeing what you need to 'cut' it's not possible to say what would be the best means to complete this task.... i.e. How many dots / lines in your job.... Do you need to cut the items out in addition to 'engraving' or 'drawing' a design.. I would imagine so.. My gut feeling would lean towards laser cutting... it's most likely to meet precision / speed requirement. there would be no 'tooling' issues... the item will likely need much less (if any) finishing when laser 'cut'. This is the type of work I would send out to an established manufacturer rather than try to buy in the 'right' machine to do it.... it would be far more cost effective... and you would also then sub-contract the potential problems, failures, machine wear-and-tear, breakdowns, process development and deadline issues... There is some loss of meaning in the translation... Obviously.. if the choice is between laser or 'strawberry' then I'd go with laser.. :D Hope this helps... Translation:- English to Portuguese - Google Olá, se a tradução estiver correta, você tarefa desafiadora. Infelizmente, existem demasiadas incógnitas para fornecer qualquer resposta real. Existem algumas coisas que devem orientar a sua decisão e posso falar para aqueles um pouco mais significativa. Por exemplo... Um prazo de 50 dias para uma quantidade de 50 mil itens. (47 dias pelo tempo que estou respondendo). (47 x 24 x 60 x 60) = 4060800 segundos / 50.000 = 81.216 segundos por item se você gerenciar para dormir comer e fazer tudo em dizer 8 horas por dia... e sem dias off ... então isso corta a por item tempo até aproximadamente 55 segundos por item.. e o trabalho levaria cerca de 47 dias.. com o subsídio para falhas, defeitos de stock desagregações ou quaisquer outros problemas. A quantidade real de stock que teria necessidade de processo é de cerca de 1 folhas e meia de 'standard' 1200 x 2400 mm MDF. Sem ver o que você precisa para "cortar" não é possível dizer qual seria o melhor meio para concluir esta tarefa... ou seja quantos pontos / linhas no seu trabalho... Você precisa para cortar os itens fora além de "gravura' ou 'Método' um design.. Eu poderia imaginar assim.. A minha profunda sensação seria no sentido de corte a laser magra... é mais provável para atender precision / requisito de velocidade. não haveria "ferramenta" temas... o item provavelmente precisará de muito menos (se houver) acabamento a laser quando "cortar". Este é o tipo de trabalho que eu iria enviar para um fabricante estabelecido em vez de tentar comprar o "direito" máquina para fazê-lo .... seria muito mais eficaz em termos de custos... e você também então sub-contrato os potenciais problemas, falhas, máquina desgaste e rasgões, avarias, o processo de desenvolvimento e questões de prazo... Há alguma perda de significado na tradução... Obviamente.. se a escolha é entre a laser ou 'Strawberry" então eu vá com laser. :D espero que isso ajude...

muito bom. onde posso conseguir este software

[@cncfreeorg]

Translation: very good. Where can I get this software? Reply: Olá, Obrigado pelas suas amáveis palavras. Links para o software estão na descrição. Hi there, thanks for your kind words. Links to the software are in the description. Hope this helps

[@cncfreeorg]

Just to say... The best place to check for links to featured applications is always the video description. I haven't updated cnc4free.org for some considerable time.. so latest info, software, techniques are not currently represented at the site. I do have some plans for cnc4free.org in the near future.. at which point info related to new and future KZbin channel content will be on the site. Hope this helps.

Hello, the halftoner 2.1 link doesn't work

[@cncfreeorg]

Hi there, I've updated the link in the description to one I tested as working today. Suggest you get it while it's still there. Hope this helps
