Proudly Made In The USAThe Ultimate Solution for Changing Nozzles?
The J-Head Farmer hotend is a versatile and reliable tool for your 3D Printer that allows you to easily change nozzle sizes on your 3D printer. With its ability to use standard nozzles and swap kits, the J-Head Farmer offers a range of options for different printing needs.
Swapping Nozzles?
One of the major benefits of the J-Head Farmer is its use of standard nozzles, which can be easily replaced or upgraded to different materials. This means that you can choose the right nozzle for your specific printing needs, whether it's printing with abrasive filaments or simply having a spare nozzle ready in case of a clog or jam.
For example, if you're printing with abrasive filaments like carbon fiber or glow in the dark filament, you might want to consider using a nozzle made of a more durable material like hardened steel or tungsten carbide. These materials are able to withstand the wear and tear that comes with printing with abrasive filaments, ensuring a longer lifespan for your nozzle.
On the other hand, if you're just looking for a spare nozzle to have on hand in case of a clog or jam, you might want to consider a duplicate nozzle made of brass or stainless steel in your normal size .4 or .6mm. These materials are still durable and able to withstand the high temperatures of 3D printing, but they're also relatively inexpensive, making them a cost-effective choice for a spare nozzle.
No matter what your printing needs are, the J-Head Farmer has you covered with its ability to use different nozzle materials. And with its swap kits, it's easy to quickly and easily change out your nozzle to the size and material that you need.
To use a swap kit with the J-Head Farmer, you'll need to add 2 pin JST connectors to your heater cartridge and thermistor wires. This allows you to pre-heat tighten all of your swap kit's nozzles and have them ready to go when you need to change nozzle sizes.
To swap out a kit, you simply loosen the setscrew in the finstack, move the new kit all the way up, and then tell the printer to go to z=0. This ensures that the new kit is the same length as the first hotend, allowing you to easily switch between different nozzle sizes without any additional calibration.
"The J-Head Farmer hotend and its swap kits make it easy to quickly and easily change nozzle sizes on your printer," says 3D printing expert Nick Stratton. "Whether you want to have multiple nozzle sizes ready to go, or simply have a spare kit with your standard nozzle ready in case of an emergency, the J-Head Farmer has you covered."
But the benefits of the J-Head Farmer hotend don't stop there. Let's take a closer look at some of the key features and advantages of this popular hotend.
History of the J-Head Hotends:
The J-Head hotend has a long history in the world of 3D printing. It started sometime before 2011 it was developed as a way to reduce the number of individual parts common in use at the time. The J-Head has undergone numerous updates and improvements over the years, making it one of the most reliable and well-respected hotends on the market. There is no doubt you have heard of J-Head™ if you've spent any amount of time in the 3D Printing community, unfortunately, the name J-Head has been used by countless clone hotends in their product descriptions hoping to capitalize on the end user's familiarity with J-Head and compatibility.
One of the key innovations of the J-Head Farmer is its use of standard nozzles, which can be easily replaced or upgraded to different materials. This was a major departure from the one-piece solid construction nozzles that were previously used, and it opened up a whole new world of possibilities for 3D printing enthusiasts.
Advantages of using standard nozzles:
There are several advantages to using standard nozzles with the J-Head Farmer hotend. For one, standard nozzles are generally less expensive than one-piece solid construction nozzles, making them a more cost-effective option for those on a budget. They're also more widely available, which means you're less likely to experience delays or shortages when it comes to finding the nozzles in the size or material you need.
In addition to being more affordable and readily available, standard nozzles also offer greater flexibility in terms of material choices. With the J-Head Farmer hotend, you can choose from a variety of nozzle materials such as brass, steel, hardened steel, stainless steel, tungsten carbide, ruby, and even diamond. This allows you to select the nozzle material that is best suited for your specific printing needs, whether it's printing with abrasive filaments or simply looking for a durable and long-lasting nozzle.
"If you've spent time looking around my site at hotends.com you may notice I don't even have all of the various nozzle material options available yet but the fact that J-Head uses standard nozzles also means that you will be able to use all of your existing nozzles you've poured hard earned money into"

How to install and use swap kits:
Installing and using swap kits with the J-Head Farmer hotend is a simple and straightforward process. Here's how to do it:
- First, you'll need to add 2 pin JST connectors to your heater cartridge and thermistor wires. This will allow you to pre-heat tighten all of your swap kits and have them ready to go when you need to change nozzle sizes.
- Next, loosen the setscrew in the finstack and remove the existing swap kit, then move the new kit all the way up and tighten the setscrew back down.
- Then, tell the printer to go to z=0 and loosen the setscrew again and drop the swap kit down to the print bed, and re-tighten the setscrew. This ensures that the new kit is the same length as the first hotend, allowing you to easily switch between different nozzle sizes without any additional calibration.
- Once the new kit is in place, you can begin printing as normal.
It's worth noting that it's always a good idea to clean and maintain your hotend regularly to ensure optimal performance. This includes cleaning the nozzle, heater block, and other components to remove any build-up or debris.
Tips for maintaining and cleaning your hotend:
Maintaining and cleaning your J-Head Farmer hotend is essential to ensure optimal performance and a long lifespan. Here are a few tips to keep in mind:
- Clean the nozzle regularly to remove any build-up or debris that may be hindering your print quality. You can use a nozzle cleaning tool or a small wire brush to scrub the nozzle and remove any blockages.
- Use a cleaning filament to remove any stubborn residues from the nozzle. Simply heat up the nozzle and run the cleaning filament through it to break up and remove any stuck-on material.
- Keep the heater block clean by using a soft brass bristle brush to remove debris and built up residue from baked on filament strings etc *this can leave scratch marks on the heater block but does a good job of cleaning it off.
- Regularly inspect the J-Head Farmer hotend for any signs of wear or damage, and replace any worn or damaged parts as needed which we of course offer replacement parts.
By following these simple maintenance and cleaning tips, you can help ensure that your J-Head Farmer hotend is always in top working condition.
Comparison to other hotends:
The J-Head Farmer hotend is often compared to other popular hotends on the market, such as the E3D V6, the Slice Engineering Mosquito, and the LulzBot Hexagon. So how does the J-Head Farmer stack up against the others?
One of the key advantages of the J-Head Farmer is its ability to use standard nozzles, which can be easily replaced or upgraded to different materials.
